hey buddy...
ya know..im 20..and well.....i dont really look it...although ive facial hair..i still have a bit of a baby face...
i had the very same idea.....doing weights....getting a brad pitt body...boosting your confidence etc etc......
theres good and points to consider...
the bad:
you would be changing the way you are....god intended you to look that way.....hence..not being yourself for the sake of a confidence boost
you could get cocky....as what happened to me for a short while.....you see a bit of muscle build up and hey...you think your the dogs bollix!! (dead cool).......
the good:
there obvious......nicer bod.....might get more glances off the girls........
i realised weights werent the answear.....if you think pesimistically all the time...you'll always think low of yourself.....thinking positivly...alothough things being s h i t t y as they are........will help you....gaurnteed........
you cant expect all women to like you.......being yourself and whatever women responds to it....snatch it up...
i know it sounds alot to take on now.....but trust me bud...you are still young and plenty of potential is still in you.....
im not an ugly guy......and i dont treat anyone mean....like you...im a 'nice' guy.......always doing nice things etc.......just like you...the confidence in me is crap.........just learn to boost what you already have........ive tried doing it and its not turning out so bad....
i cant think of much now...but if you want to ask anything else.....fire away
