The red pill of course (if it cures, if it halt i already have propecia).
I won't care about a mystical self confidence. It won't give me simple pleasures like being able to attract a girl. Don't get me wrong, i don't wanna be Di Caprio, i just want to keep my average ability (wich is not that great), to attract some girls, without feeling i have to run the race with some sort of great handicap, and to feel okay with myself without being delusional.
I prefer a rationnal self-confidence than no-confidence (i mean a confidence based on my achievments in the areas of life i care about the most : one of them is girls), but i'll take the achievments and the simple and great pleasures of life with no-confidence rather than a magical self-confidence that doesn't change a **** in my life and wich is condemned to go away unless i'm delusional.
This question is just a variant of "Would you rather be intelligent and feel pain or stupid/ignorant but happy", the second one is called delusion. You may be happy but you won't achieve anything in life, and won't be able to work on your tangible situation because you're looking at it only through a deforming mirror. Actually i don't even feel that happiness can be genuine if it's never challenged. It's the same thing without self-confidence, always feeling confident while "deserving it" will just make you farcical, creating a big distorsion between who you are/what you do about your life and your evaluation of that. I don't think this kind of self-confidence is worth having.
