Here is how the universe works, whether it is in business or personal relationships. The more you second guess, doubt, and try to cover everything that could go wrong “before” you enter it, the more you will discover the need to do it. However the more you approach life and each new connection with open arms and trust, the more positive and elevating souls will enter your path in which none of the doubt is needed. Even the negative moments are positive lessons.
When our hopes for performance are not completely met, realistic optimism involves accepting what cannot now be changed, rather than condemning or second-guessing ourselves. Focusing on the successful aspects of performance (even when the success is modest) promotes positive affect, reduces self-doubt, and helps to maintain motivation (e.g., McFarland & Ross, 1982).... Nevertheless, realistic optimism does not include or imply expectations that things will improve on their own. Wishful thinking of this sort typically has no reliable supporting evidence. Instead, the opportunity-seeking component of realistic optimism motivates efforts to improve future performances on the basis of what has been learned from past performances.
When you get down to it, though, explaining what you believe isn't all that easy. If you say that you believe something to be true, you might mean one of two things—that you're still weighing the alternatives, or that you accept it as a fact. I don't logically see how one single word can have contradictory definitions, but emotionally, I completely understand. Because there are times I think what I am doing is right, and there are other times I second-guess myself every step of the way.
