Don't be too hard on yourself sumi. I quit once for about 18 years and stupidly started again. Too much to deal with: divorce, early retirement, selling a house, moving to a strange city, my dad dying, and all that happened in one year. That's what got me back into it again, I was shaken and it seemed to be the one thing to hold me together (or something to hold on to). Some day I'll quit again. Ken's right, the biggest hurdle is mental.
