I got fat because I had a crappy diet of cheap food because I grew up in poverty. Also, I am a toe-walker, which disables me from running and jumping. I broke my arm when I was in 3rd grade (or there abouts) and it took a lot of wind out of wanting to BE physical. I broke it when I slipped off the monkey bars because I had finally figured out how to do them for the first time and then I did it a bunch and fell. That also bored a lesson into not exerting effort into things because of a fear of not being good enough anyways. This persisted until 2012.
Crypto: My Achilles tendons are too short, which brings my heels permanently off the ground and prevents be from being able to bring my toes upwards towards my shin. Subsequently, that muscle that runs along the shin is weak because I can't really use it. It makes it more difficult to keep balance when still and makes climbing stairs, doing squats and "lifting with my legs" something else. There is no solution, because I am too old for a doctor to want to approve operation on me. I've even tried stretching the tendon with a strap tied around the ball of the foot and hauling back with all I've got. It's like iron, I swear.
EDIT: I do have psychological issues - motivation related, anyways.
One answer could be that my family is incredibly passive aggressive.
