Everybody can become a successful person & educated thinker by using their creative and critical thinking abilities. Being creative is not the same as being artistic. People can be creative in the areas other than arts. Creative is "a state of mind and a way of life." We all can be creative by investing our unique perspective or our talents to different aspects of our life.
The idea why we think that we are not creative because our creative abilities are suppressed by the reality; by our fear of failure; and also by our self-criticism. We afraid that our creative activities will get some undesirable consequence. Instead of avoiding self-defeating criticism, we need to face and get through it. In order to gain support from other people and to resume our confidence, we can share our ideas and feelings with other people.
