I'm glad you have come back. It seems too many cave and aren't man enough to come back, admit your mistake and go forward from there (which you have done) . A couple points (which you likely already know)
So much of quitting is mental, rage is useful at first but it won't keep you going forever.
Most if not all of us have weak moments, I know I do. I don't enjoy posting every day, but it is the cost of staying quit. I would love to say I could stay quit if I no longer posted roll, but I can't.
Print the contract to quit, it has been a great reminder of why I want to be quit each day.
Do some things differently than last time, something about your last attempt was flawed, figure out what and change it.
Don't underestimate attitude, I've included a favorite quote:
Life's battles don't always go to the stronger or faster man. But sooner or later the man who wins, is the man who thinks he can -V Lombardi
I'm quit with you today.
