One of the things that really gets in the way of creativity is the way that we think about ourselves. We have two choices: we can imagine ourselves as ‘artists’ or as ‘non artists’ and in many ways this determines how the rest of the world sees us as well. When you conceive of yourself as an artist (or creative) person, the rest of the world joins in and agrees with you. The way you see yourself matters and the way you describe yourself is important and influential.
In his book “Steal like an Artist” Austin Kleon talks about the need to claim your space. He even goes so far as to suggest that you collect pictures of your favourite artists and imagine yourself as part of a lineage of artists.
This is a hard idea to come to grips with if you are accustomed to thinking about yourself as a non-creative person. It seems a bit bold to me, but I don’t think there is any harm in it. If it gives you confidence to see yourself as part of a cohort of creative people, then that might just be the thing you need to actually try out some of your ideas.
