It's funny, in "real life" I "need" a comfortable chair, and my fancy easel, and my special drawing paper that's just the right size and weight. Well, maybe it's not so funny, ya know? On the mission trip to Baja, I was perfectly content in the BLAZING sun, no shade for miles, sitting on two concrete blocks in the middle of a sandy field, drawing on a sketchbook barely bigger than my hand. And the people loved the drawings, as a bonus.
When you're using your talents for the one who gave them to you, it's incredibly fulfilling.
I told my wife, I've never felt so fulfilled... so confident that I knew I was in the right place, at the right time, doing the right thing... in my entire life.
