I'm still praying over whether to semi-retire this year and just work on projects I'm interested in, or push it three more years. Cool thing is that if I decide to slow down, I can reduce my hourly rate and take projects that aren't fast-tracked.
I never miss schedule milestones but I'm getting too old for the stress. Last year's hip disaster and the neuropathy that took away the use of one hand suggests that while I'm charming, witty, handsome, brilliant, talented and otherwise blessed beyond just deserts... I may be mortal.
