You are responsible for your life and all the things in it. The actions you take are yours and yours alone.
You can't blame anyone for what you DO.

Socio-economic class is a compound word for a reason. It's about being poor AND around shit people.
For many reasons, it ain't the same thing.
In short, I grow more sympathetic to effect of circumstances. Maybe I'm just lucky I made it out.
