[snowskate]

For me, 31, i've had my crisis arise out of worry that I haven't been doing what I really wanted to. My mid life crisis, luckily came early.

I've got a great paying job with tons of freedom and still don't like it. I guess I work to live at this point. 10 days after the Chicago Marathon my appendix burst AND JNJ had lay offs at the same time in 2004; I then deepened my involvement with physical "progressive" activities (snowboarding/skateboarding) that require me to raise my personal bar one season at a time. this has restored some balance.
Since then, I realized not to take life so seriously and let things slide while at the same time focusing on progressing my technical abilities.

My athleticism won't last forever, and although I'm still not at the top of my game, I appreciate it in the present moment. When the time comes for my skills to degrade, hopefully, I've gave it my best shot and can accept a slow regression in abilities.
I'll always have my mind and competitive drive, but I have to use my body while I can. Detailing is a great "progressive" outlet, but I feel I can detail a car well into old age.

The ultimate would be to mix "what gets you early and eagerly" out of bed with a career.
