I think part of it has to relate to what you enjoy doing. I enjoy few things more than reaching the time of day when work clothes can come off, dirty old shirt goes on, lithium ion tool drill comes out and the circular saw is plugged in. It's the best relaxation I have found, and unlike my real job, I can actually achieve something without other screwing it up and the results are measurable. Don't ask about the accidents, stitches and cost/time blowouts.
