I see all these people asking how they could control the world to avoid sub-optimal social outcomes. How do I force a person to fall in love with me? How do I know in advance if a person is good at sex? How do I force my relationship to go according to my plan? And so on.

It doesn't work that way in real life. You can't press "up, down, left, right, A, start," to open up the relationship debug menu.

You can't know in advance how good a sex or relationship partner someone will be. You'll have to take a chance on them. You can't force a relationship to go according to plan, because life is always going to throw unpredictable shit at you. You'll have to learn to adapt. You can't manipulate someone into loving you without sacrificing the experience of authentic mutual love. If you try, you're just cheating yourself out of potential happiness. There is no reward without risk.

And finally, you can't really control what you're attracted to. The heart and the genitals want what they want.

What you can control is your mindset, how you react to the world and to your own urges. You can control your own behavior. You can improve your odds of success by knowing RP truths and building yourself up. But at the end of the day, all you can do is put your best foot forward, roll the dice, and keep yourself from freaking out if you lose.

EDIT: Since I can't respond to everyone making the same point at once -- People have rightly been telling me that no one is helpless and there's shit you can do to improve your chances. Of course that's true. What I was calling out in this OP is more the spergy analysis paralysis that crops up on this subreddit, when people who are terrified of suboptimal outcomes try to flowchart everything in advance, instead of going out and taking risks. I maintain that the higher the risk, the sweeter the reward.
