I pretty much spent the whole day listening to Bobby Chiu's podcasts (thanks for the link Mark ;) ). His personality is something to be inspired by, with that mentality I have no doubt he could succeed at anything- art related or not.

Symmetry is something that I can't seem to get right, I'm not really sure how to solve that one just yet.
