Hehe, pretty cool. One of the things that I am working on is learning to forgive myself for not being a super genius at everything. It is one of the things that I've gotten out of the hours of meditation that I've accumulated. I am super hard on myself!
Sculpting is an awesome way to get out creative frustrations.. There are no rules unless you impose them on yourself!
Cool sculptures by the way. I think I will try that myself; quickly shaping items to exercise the mind. I will probably come up with some funny cartoony stuff.
