Attitudes for Creativity

I just remember the Bernards Shaw's quote:" You see things, and you say, "Why?" But I dream things that never were, and I say "Why not?"
I am sure if the creativity can be learned anyway, a lot of people just born to be creative...
maybe someone can see this link listing 9 attitudes for creative people, and tell me if creativity can be learned or not.
the attitudes as listed by the link are as follows:

1. Curiosity

"What if?", "Why?", "Why Not?"...

2. Seeing Problems as Interesting and Acceptable

Creative people see problems as a natural and normal part of life - in fact they often have a fascination with problems and are drawn to them.

3. Confronting Challenge

Asking ‘how can I overcome this’?

4. Constructive Discontent

Awareness of what’s wrong with the world around, then let it be a motivation to doing something constructive.

5. Optimism

They are not always happy, they can be depressed. but in general they know that some problems can be solved.

6. Suspending Judgment

The ability to hold off on judging or critiquing an idea is important in the process of creativity. Often great ideas start as crazy ones - if critique is applied too early the idea will be killed and never developed into something useful and useable.

7. Seeing Hurdles as leading to improvements and solutions

overcome the problems in the creative process itself.

8. Perseverance

Stick-ability is key. stick to your idea....

9. Flexible Imagination

amazing ability to see a problem or challenge and it’s many potential solutions simultaneously
