Curiosity:
Asking yourself questions like: “What would happen if?”, “Why?”, “I wonder if…” to make your imagination fly freely.
Seeing problems with lightheartedness:
Most of the time when we see ourselves in front of a problem,  we see it like something unacceptable in our lives. Creative individuals see problems like fascinating challenges to overcome.

Facing problems:
Most of the creative ideas have been developed throughout history, when people face their fears and problems.

Positive acceptance:
Accepting when something is wrong and correct it.

Optimism:
For a creative individual, there ain’t no mountain to high to climb.

Do not judge:
The really “crazy” ideas tend to be the best. Don’t kill your ideas with too harsh critics.

Seeing obstacles like a way for a solution not the end of the world:
While we work, many times our ideas are developed, we might make tons of mistakes, but that’s when the real magic starts to happen.

Perseverance:
Of outmost importance.

Flexibility:
Highly creative individuals have the capacity can bend and turn ideas around in the finding of solutions for their obstacles.
