When do you feel most alive/energized?

Are you at work, at play, at rest?

I feel the most alive right after accomplishing something very difficult. At work it may be when I figure out a difficult bug in my code (or someone else’s). At play, it might be after successfully recovering an animal that was really hard to find, shoot, and track. At rest, it could be that moment when I finally find the right position for my leg in “half pigeon” (yoga) that allows me to relax into the pose and deepen the stretch.

What does it for you?
