This is a cool short TED video of the Artist Phil Hanson. He describes how he overcame his biggest limitations by embracing them:

I’m sure we have all noticed at some points in our lives how limitations can make us think more creatively – in fact, it’s much harder to think creatively if our options are unlimited!
The reason for that is that our natural way of thinking is very efficient – rather than very creative – by following the strongest associations we’ve built throughout our lifetime of learning and thinking. In order to become more creative, we sometimes need to be forced out of that natural (more efficient and comfortable!) way of thinking…

Phil Hansen’s example shows very nicely how embracing those detours can be a very powerful creativity-enhancing experience.

The beauty of it: it works for all of us, not just for artists!
The problem…: it’s hard!
