If you keep making the same mistakes, surrounding yourself with the same type of people in the same type of environment, I can assure you that nothing will change regardless of how much you talk about changing.
When shit hits the fan, stop pretending that you're "sick of it all" and need to change. You're just saying this to make yourself feel better between your lowest moments of self-destruction. If you want to change, then CHANGE for fuck sakes. Stop being such a coward and deal with your issues.
Change for a change would be nice.
