If you read the intro I just posted it may have some resonance. I was having similar thoughts about my age and life path. And the universe delivered a ride to my second Burning Man as the co-pilot with a wonderful 64-year-old camp-mate who was having a very similar experience - a kind of re-awakening, finding himself again after marriage, parenthood, etc. 15 hours of driving with him really put things in perspective - from where he sits, I look like a young 41-year-old whippersnapper!
