I have, but not for post leaving the WT reasons or health or that matter
I just decided about 4 years ago that there was no way i was going to get ahead, buy a house etc.
I decided to start my own business after working 40 hours a week was not making enough to get by on an leave anything left for fun. I found i could make a good income on 3 days a week work. I could make more, i just don't want to. Not only do i want my 4 day weekends for more important stuff, i resent having to give more to the tax man if i do.
If i cant be bothered working on any given day or just feel slack half way thru a day, i can stop and do it another day.
When i met my wife, we find we have the same attitude... neither of us are interested in hopping on the mouse wheel like so many others already are and busting ourselves for material gain and to serve the system like worker ants. We have just bought a cheap country house, that will cost no more than out current rent and not require us to work more either.
I stopped pushing myself because life is to short to spend doing things you dont want to do.
