How do I change my evil ways?

I’m tired of being so unmotivated. Sloth is a deadly sin, and I am quite slothful these days. Is it really as easy as strapping on the running shoes and going for it. This really is a problem for me, I’m not doing anything productive, positive with my time. Even though I am stuck here on this island, I can still make better of it. I feel like my only option is to continue with Government Assisstance, or be a bum on the street. I’m a Republican damn it, I should be able to support myself. I was very high when I registered as a Republican. I’m a felon anyways so it’s not like I can vote. Fuck it, I’m going to at least get in good shape. How do I start an excercise regiment?
