Have stopped plenty of times. Today, for the first time, I'm quitting. I'm scared that I won't be able to function as usual, but more scared that my awesome wife won't have her best friend to grow old with and that my daughter won't have someone to walk her down the aisle, and that my son won't have someone to teach him how to switch-hit.
I've been a ninja for 20 years. Crazy when I write that down. It's really a few months more than 20 years. What a jackass I am.
The thing that I'm most scared of, I think, it driving to work on Monday morning. Since I'm ninja, I only sneak away to have a dip or two per day on the weekends, so my commute Monday morning I look foward to being able to pack my lip, take a deep breath, and start living in the "real world" all over again.
I'm rambling but that's because I'm writing to myself as much as anything about wanting to quit/needing to quit; now I've got to translate that into one day at a time QUIT. No, now I've got a new thought on what I'm scaredest of: I've stopped before, but what am I going to do to make sure I don't re-start again a few weeks down the road? I don't know--I've got to find it.
