Motivation/Inspiration: What drives you?

[Linus]

So I've been trying to get back my motivation I used to have a while ago. Lately, I've been feeling burnt and worn. Sometimes it's justified (working 60-80 hours a week, especially on the road); and sometimes not so much. I've been trying to figure out what it is that is holding me back (I know it's me but I'm not sure what "me" is doing to cause this). I still have desires to do my old long distance bicycle touring but I haven't been on any of my bikes for any consistent or long periods in the last 3-5 years. A couple of years ago I got into minimalist/barefoot running for a solid 3 months or so and then stopped.

And it's not just exercise. I'm currently under contract to write a technical certification book and have the worst writer's block at time. I stare at the page and get maybe one or two paragraphs (if I'm lucky) done. I've gotten about 40 pages done (roughly 2-3 decent starts on chapters and one that needs a lot more flushing out). My publisher wants this done by Jan 1, 2013 -- which may seem like a long ways away but, in reality, is creeping up fast (and will speed by faster).

So I think one of the things that I'm feeling is missing is motivation or inspiration. What do you do to motivate yourself on life (whether exercise, household chores, work, etc.)? What do you do to inspire yourself (could be religious, non-religious, visual or audio)?

As my sis says "Find joy y'all". So how do you find those things that create joy and the want/will to do more?
