I don't know what happened but after suffering from being fat in adolescence and going to a really shitty high school full of broke/ghetto trash that didn't care about life, even as a guy who is now in his 20s, I have this feeling of being a low energy procrastinator that wastes time and isn't alert or active. I have days where I just go through the days and even when it comes to socializing, there are days where I am just not upbeat or excited about it.

I feel like there might be something wrong with me here. Most of the day I spent wasting time browsing the web and occasionally going out for a walk or going to the gym but I am just not a very active and lively person.

How can I change this?
