The resolutions that have worked for me are usually after a major life changing event.
The biggest one occured the winter of 1999. I had spent many years complaining about my pointless career and dismall life in my home town. That winter my youngest brother died. At the funeral I decided I had enough of my own bull shit. My brother's death put everything into perspective. Mainly that the things I hated most in my life were fixable and there were more important things to worry about. Thus, at the funeral I resolved to fix my life and start enjoying it. The end result was quitting my job and moving to Denver. 4 years later I have a decent job, a new baby, and a new house.
Sometimes it takes a traumatic event to push you into doing something about your problems.
