I am not over 50 or anywhere near that, but my life advice so far is: Take more risks, don't get stuck in your comfort zone, and hit the gym regularly.
And most importantly, 'Money matters.'
Everyday, alarms for everything.
Back / legs 1 day
2nd day chest / shoulders
30 days a month
Write own software frameworks to create own programs quickly.
Fuck everything that moves and has common sense. Take risk, so you might get a child one day.
Of course if you don't fantasize about women and sex all you'll fantasize about is living in monastery and away from society as there's nothing useful in society beyond personal relationships.
You might become someone like incel or gymcel. Thinking about ladies almost always results in fantasies, so if you want to stop fantasizing, you have to stop thinking of women. And that'll lead you to reddit extremists. At that point you might get depressed and isolate yourself feeling unaccepted by women which is ridiculous to think but that's what happens once you try to reject whole gender.
One of the most popular ways to destroy one's life and cause collapse of civilization / country hammering natural increase is to promote views like this.
I tried it. It doesn't work to not fantasize. Your life will be boring as hell without fantasy and imagination.
If money maker stops dreaming, he will lose touch with big ideas and go white hat then blame it on someone else.
The basis of black hat philosophy is you can do anything as long as it's legal. You don't have to abstain from pleasure to create good life. You don't stop becoming your best version because someone labels what you do as unethical or immoral.
