All of my advice is good actually, and I'm blunt. Young kids are sensitive bitches. You have to be honest with yourself, the same way I'm honest with you. You are a pussy. You can get stronger, you can get better at whatever it is that you do.
But to try to convince yourself that you're not a pussy, or that you're ok with being a pussy is sad.
I used to be a pussy. I was 100lbs at 22 years old, and scared shitless the first time I walked in a gym. I could have comforted myself with how I thought being a weak pussy was ok, but I met a dude like the 2nd week of me going that was a powerlifting champion and he told me I was a pussy, and that I should change that. We became great friends and he taught me how to make myself strong.
Don't be so sensitive. I know this is the "kill myself if somebody is mean to me" era, but suck it up.
