My personal challenge as an artist has been having a day job which is intellectually satisfying and fun - and thus can easily supplant the desire to make art.
Real art is one of the most powerful forces in the rise of mankind, and he who renders it accessible to as many people as possible is a benefactor of humanity.
The world is going on a high-speed connection; the Arab revolution is still dial-up. So we have to give it a little time to download. Regimes come and go, but art endures.
