Trust your intuition.
That will cover everything.
One of the things we learn on this forum is to wake up to how we have been conditioned, as men in society, as sons in our families, as members of churches, as consumers bathed in advertising since and early age, and especially today, as operant conditioned adjuncts to our electronic devices.
We can even be conditioned internally, with our own plans and desires, that have been derived from the dark wave of external pressure.
I didn't even start listening to my own intuition, really, until I was in my thirties, and if you had asked me in my twenties, I would have dismissed the concept as fairy dust, and told you I was a thinker, not a feeler.
Without intuition, this is what life is like: You cannot escape programming, and your own internal landscape will be an amalgam of things that have been imposed on you from the without. Even when you think you are venturing out into the world under your own steam, you will be acting out some program that was presented to you whole cloth from an external source.
You will think you are rebelling against you family, and end up in a relationship with some girl who is just like mom. You may change the external aspects of things you don't like, for example refusing to choose a career like dear old unhappy dad's, only to end up just like him because the subconscious dynamics will turn out to be no different because even though you are a programmer instead of a dry waller, you still have internalized all of the unspoken assumptions and practices that you never consciously learned, but only absorbed in a million ways by being in proximity to people who thought and acted in a certain way.
So what happens?
You consciously prepare a life for yourself, you make plans, chart it out, and get on with it, and somehow, incrementally, you end up chained to a course of action that your soul is screaming against. Only you don't realize it, because you don't know you have a soul, and here I am using the word soul as short hand for the authentic inner self, so there is no need to attach a religious/metaphysical meaning to it.
Your soul/intuition is fighting against the circumstances of your life, and yet you have no concept of even having a gut instinct at all, so all you have is a vague sense that something isn't right, and you have no idea what to do about it.
You soldier on until it gets to be too much, because what you have been doing is suppressing the deeper part of yourself, and then you have some sort of inappropriate outburst that blows things up in what can be termed, diplomatically, a less than optimal way. You blow up a job, a relationship, standing in a community, because you didn't ever have access to your own inner compass.
I didn't actively start cultivating my intuition until I was in my late twenties, and I cannot honestly say that I ever have any regrets about following it, though there are a couple of caveats about this course of action. On the flip-side, there are many many times when I suppressed that inner voice, and some of the deepest regrets I do have come from failing to listen.
It is not an easy course to chart, if it is new to you, and it will take practice and time to separate out your intuition from your programming, your own prejudices, and even your own whims. Lots of false starts and blind alleys down this way. Eventually though, even if you are like me, someone charting new territory, you will eventually learn to separate the wheat from the chaff, and learn to hone in, reliably on genuine intuition.
Intuition is like a woman, and it does not arrive, despite what the New Age gurus will tell you, in time or on demand, and many will be the time that you are listening fiercely to a voice that never comes, and you will be on your own, figuring it out as you go. It will, hoe-ever, heh, pop when you least expect it, to deliver you from some serious bad decisions right in the nick of time.
One example I can give you comes from when I was raising my step kids, and my programming was, they aren't my kids, so I will always defer to their mom, because "a mother always knows," as the programming went, at that time, in my mind. I actively suppressed my own instincts as a father because I didn't want to be overbearing or authoritarian. This was, by the way, years ago, back when Red Pill thinking was unknown, and men weren't really getting online and comparing experiences, so most guys were on their own figuring things out, lonely solitary figures, not really knowing how to push back against monolithic Blue Pill programming.
My only regrets came from the times I didn't listen to my intuitions as a father, which were many, and I cannot say that there was ever a time when I followed what I instinctively knew, and found it was a bad move.
The trick is, that the mind has to follow the intuition, and not the other way around.
Sometimes, you get an intuition, and you act on it instantly, and it is the right move. Much better though, for the most part, to actually hear the intuition at all, which is what takes practice, and then to put your mind to work figuring out the best way to implement what your gut is telling you, instead of taking the bad deal for as long as you can, and then having a dramatic beta outburst of anger, and blowing things up dramatically.
I now believe that all of the things that we learn online, and teach each other, already exist inside each mans soul, that we are naturally Red Pilled in the most life and culture affirming sense of that term, it is just that we have been trained not to listen to the inner voice that can reliably guide us if we let it.
I can even look back on my own life and see moments from relative youth and even childhood where my intuition was screaming at me through thoughts, impulses, even actual dreams, and sometimes I had the guts to follow it, and sometimes I didn't. I can't see any times when following my gut was a bad move. The catch is, it takes guts to follow your gut, and it may up end everything. It may not too, it may make things easier, though there is no guarantee of that.
Now, about those caveats.
Your intuition is like an inner spark of the divine, and whether or not you call it God guiding you, or you call it your subconscious mind figuring things out on a deep level is immaterial, the fact is that it works reliably once you can sort out genuine intuition from proclivities and whims, and very often the hallmark of a genuine intuition is that it goes against what your mind is telling you, and it goes against your native preferences and desires.
And that is a big caveat.
Your intuition will not necessarily lead you to an easier time of it. It isn't a simple concept like, I was going to work one day, and my intuition told me not to, and I didn't and I was lucky because a disgruntled guy with a gun showed up that day and I was lucky I listened. It can work on that level, and protect your ass from bad people and bad relationships, and bad situations, no doubt.
The problem is that your intuition can lead you into situations that drop you right in the middle of firestorms you never would have sought out otherwise too. It will not promise you better superficial outcomes, not at all.
The only thing that can be said reliably about intuition is that it will teach you what life is all about.
It will give your life meaning and direction, even if you don't reap the lessons until years later.
There is no simple syllogism or thread of logic that can justify following your intuition, so I won't even try to put one forward.
All I can say is that no matter the pain or trials of my life, whenever I look back at any time in my life, all of my regrets came from times when I didn't follow my intuition, and no regrets came from the times that I did.
This path clearly isn't for everyone, and many of the rewards are entirely internal.
I have many people in my life who think I am merely crazy, lazy, or bad, and have been sustained, at times, only by my own trust in some obscure inner prompting, and all I can say is that no matter how it appeared on the surface, it has been worth it to me.
But then again, you asked what I would have said to *my* younger self, and this is it, trust your intuition more than you do now, hop on the intuition train as fully as you can and as soon as you can, because the internal rewards will be worthy it.
That's what I would have told my younger self. Whether or not this advice is any good for any one else's current young self is anyone's guess.
You'll just have to trust your own intuition on that one, or your own rational mind, whatever the case may be.
