Pessimists hang out together with other pessimists. If you have a bunch of pessimists in your life, guess what that says about you. Optimists do not depend upon luck for their good fortune, because they understand that nothing in the universe happens by luck or accident. Pessimists rip themselves off by erroneously believing and behaving as if they could benefit at the expense of others, thereby not fully accessing the greater potential that optimists naturally access. Optimists don't get pushed out of shape the way pessimists do when obstacles appear, because optimists realize that no obstacle is insurmountable, thereby naturally overcoming obstacles pessimists continue to be stymied by.
Optimists look for opportunities to be supportive, encouraging, and optimistic to others.
Therefore, optimists are more inclined to have a creative intuitive edge over pessimists when it comes to financial investments.
