Welcome back. If you're bored, read some of my first posts. I actually started a thread once saying "How do you start caring again"... After some sober days, it's funny, it just sort of worked out. I tend to care about life more when I'm not drinking poison in high amounts. Moreover, I'm on my third username here.
The bottom line is ever decision requires action. We must follow up our decision to do anything, with action. Otherwise it means very little. I made a decision to quit more times than I can count. It wasn't until I took actions on a daily basis to support that decision, that made my life change.
