Still, I feel some desire to fix my brain

Isn't it great to be human, and unconsciously feel that need to be better? lol

Anyway, I'm glad to tell you that of course you can improve. There's an old lie that once you reach 18, your mind stops developing, which simply isn't true. You have three years more of "youthful" neuroplasticity, and even after that you can change your habits, routines, addictions with human effort.

You also state that you're not good with girls, hey, suggestion, imagine if you believed you were, genuinely.

But another thing is that the superpowers is more like an exaggeration, at least in most cases. Like, you said the last time you were with a girl it wouldn't go up, imagine after a month or two of nofap you could do that! Would that be a return to normalcy or a superpower? Your choice to believe!

Now there are other benefits, ones I've noticed recently are;

• A clearer mind, meaning it's easier to think, to empathise, to imagine.
• Easier to socialise, skills don't come, but the will to do does.
• Time. the time I spent whacking the walrus is now spent sleeping, working, meditating, reading, playing the piano, anything except parasitic pornography!

At the end of the day, of course you can, don't be afraid to do it!
