About a week ago I finally nailed an asian crab cake dish I've been working on.  The right sauce totally made it.  That was passion.

It's sort of an ongoing thing, but I've been trying to read most of the existentialist writers.  I found new author I didn't know of before, Knut Hamsun, and the guy totally rocks.  That was sort of passionate, but not really because reading is a more passive experience.

I become very passionate when I'm playing guitar and creating new songs.  Unfortunately, I've not been inspired to play lately.  I'm not sure why but it will come back eventually.  

Another passion of mine that never relents is my prostate cancer prevention regimen.  I've been passionately preventing prostate cancer since my early teens.
