Yesterday, I ran across an article somewhere talking about if creativity can be taught or if it's just genetics... Just googling Creativity: Genetics vs Training, there are so many different articles on what people think.
There are some people who say 'I don't have a creative bone in my body. I can't even draw a straight line!'
The thing is... You don't have to know how to draw a straight line to be creative. I can barely draw a straight line, circle, or what have you and I call myself a creative mind. The point of me typing this out is to be creative, I believe all you have to do is break down those barriers that tells you you can't do something.
Whether you are a musician, designer, painter, sculptor, etc... Once that barrier is broken, once you stop that doubt that you can't do something, the creativity will soar through.
I'm sure even the best of artists think they can't do something at one point or another.
