Most men in my family have street smart skills, know when to use white lies, know when someone is bullshitting them and are good at figuring out stuff and talking to people. My maternal side isnt like that, my grandpa is the most humble man I have ever known, he is always ready to selflessly help anybody at anytime but people have taken advantage of him and ripped him off aka somewhat gullible. Same for my mother and so I have picked up their traits and I dont want to be like that. Worst part is Im a tall guy with above average looks and a decent sex appeal, I notice people looking at me ofcourse on the outside though I act manly as hell but thats about it what kills me is that inside Im dumb as shit with terribly low self esteem and feel inferior to pretty much every male out there. My question is there anything I can do to overcome this and become smart or would I just be fooling myself by even trying to attempt to become someone I am not?
