Learn by Doing.
The temptation is to stay comfortably in the world of thought. Why risk the discomfort and uncertainty of results when you can stay secure in the luxury of speculation? We are socialized to do "right" instead of "wrong" and to be mindful of our actions. As children, we may have been punished for acting without thinking about the consequences. As adults, we may over think the potential negative outcomes (as a result, we may refrain from action altogether).
The Wright Brothers could not prove that the first plane would fly (until they flew). Fleming could not be certain of the effects of penicillin without introducing it to bacteria. George Washington Carver could not have completely imagined the many uses for the peanut if he had never experimented with possibility.
We learn by doing. If you do not risk for reward, you are limiting your power, potential and contributions to the world. You are not here to live small. Who does that serve?
Success or sabotage? You may only achieve success if you are willing to entertain what many categorize as failure.
Is this going to be an incredible day? What are you willing to DO to make it so? Do not think it, do it!
