I really liked what qualities you mentioned as these are not only qualities that would make one a creative person. They would also make one a better person.
I especially liked this part about humility:
The key here is letting go of ego. The more you learn to compensate for your small brain, the better you can think clearly. The humbler you are, the faster you will improve.
In some ways, it really is about getting out of our own way, isn’t it?
