Creative people can be a little weird. Great artists are often outsiders: they don't behave like us, they don't look like us and they don't think like us.

True creativity is not the preserve of people who think the same as everyone else. Frequently (but not always) this is the result of lots of weird things happening to them:

"...highly creative individuals often experience a disproportionate number of unusual and unexpected events, such as early parental loss (Martindale, 1972) or having an immigrant status (Goertzel, Goertzel, & Goertzel, 1978). Furthermore, living abroad is linked to creativity in the general population (Leung, Maddux, Galinsky, & Chiu, 2008)." (Ritter et al., 2012) 

I recently read a blog post by Dr. Dryfus on simple ways of incrementally changing your life. Basic, but also fascinating stuff.
