. IDK if I'm the right guy you want to talk to. ima type of n1gga that think looks >>> game every day of the week. hoes know within 2 seconds of glancing at you whether they will let you hit. I always seen it like athleticism (looks) vs skill (game) in AAU basketball. The more athleticism a cat may have possess , the easier it is to dominate and get attention /scholarships from schools that don't care how a n1gga don't know how to dribble or pass, just that he can do a 360 windmill....
In your current shape, your game has to be that much more sharper than a better-looking n1gga... to me, that's not fair and it is a waste of effort just to appease a bytch. in my experience, being sexually attractive (even average) and having a decent mouthpiece is better (i do OK, i can't manufracture a convo like some n1ggaz, but I will never an awkard convo w/ a chick
You got any brehs in RL you can chill with? hit the gym together and better yourself. Not for females, for YOURSELF. Yes, use girls as motivation, but not the main goal. A better body gets you more respect from not just females, but guys too. And it's an easy convo topic for girls who are looking to express their interest ("wow, do you lift weights" etc.)
for the mental part... you really need to dig deep within yourself and find 'why' you think that. it's a good 1st step that you recognize your weaknesses. maybe your parets raised you up wrong, maybe a traumatic experience, maybe bullying, bad high school experience, etc. You need to find that origin and deal with it. Either confront the problem, forgive/fight whoever wronged you, or move on. this process can't really be done in weeks. you've probably been thinking negatively so wrong, it's part of your DNA by now. it's gonna be a years-long struggle, but you will make it to the other side.
The physical and mental improvements you are going to make - don't just make them to get females.
