The solution is pretty simple. Nothing that you do has any meaning. Life is a game so try to have fun. If possible, to make that game more interesting and pleasant because it is a pretty crappy game with only one life.

If you were a woman it would be pretty simple your purpose would be baby-making but since you are a guy you have absolutely no purpose you are a god, who exists just for his own fun. By some random chances, your genes may be transferred to another generation but it is not your purpose to do it.

You probably would not complain that MMORPG game characters are all redundant or the fact that you slay a dragon changes nothing because he respawns next second. So no reason to worry about redundancy.

The thoughts like yours typically happen when your denial was about denying the fact that life is the game and you spent it doing things you don't like because of some obligation or duty to something transcendent. Later you find out that all that as a waste but you can't accept that you actually wasted 20 years of your life on pointless suffering because you are an idiot and did not notice the obvious things.
The loss is when you invest in something and all your investment is gone with no trace. denial just makes it worse, because you refuse to accept the fact that your investment is gone and continue to invest into something that already went bankrupt instead of trying to cash out whatever is still possible. But the more you deny it the worse will be your consequences.
By the way, this is even told in the bible by Jesus.


Fortunately for me, I was just lucky and dodged the bullet. I never married or had children got a pretty easy job which later transformed into a business. I would even claim extraordinary luck that I practically escaped death several times along with my relatives so nobody even got hurt. If feels like I am walking on the edge of the abyss for so long and still did not fall.
The only real problem for me is that it is not so easy to find someone to play this game of life together.
I have no regrets (besides the regret that I did not mine any bitcoins) and my only concern is that this good life is eventually going to end in one way or another. But maybe I will get lucky again and my project, which is beyond the dreams of the most delusional narcissist, worth several sextillions dollars, will succeed and I will be the person who turned the entire universe upside down. So not all hope is lost yet.

The recipe for happiness is to have hope for the best and expect the worst.
Either way, whenever your dreams will come true you will lose that dream and what you get will typically be far worse than you expected. If the dream does not come true you at least get to keep the dream.
