Creativity is not the same as positive thinking.
Positive thinking is the attitude of one who believes in the probability of a positive outcome.
Creativity is the determination to act towards a desired goal, however unconventional the means, whether the results are guaranteed or not.
If you do not believe in the power of goodness to prevail over evil, then you are probably not a positive thinker.
Creativity, on the other hand, has no belief requirements.
The creative process can be just as easily spurred along by practical necessity or curiosity as it can by belief in one’s ability to achieve a result.
Maybe things will get better, maybe they won’t. Maybe your ideas will work, maybe they won’t. Maybe you’ll have a good time, maybe you won’t. There’s no need to torture yourself over what to believe. Create and see. Live and learn. Work and watch.
You don’t need to have strong faith-filled beliefs about possible outcomes in order to be creative. All you need is the willingness to try something different.
Open-mindedness, not optimism, is the portal to new possibilities.
