The stuff that keeps you up at night rarely comes to pass. It’s self-created projections based on past experience, or lack of experience, and it’s nothing really to worry about because it’s counter-productive. Your mind is trying to prepare you, but what you are undertaking will be learned in the flow, not planned out in your head. If you don’t make trivial matters important they will cease to be important. Pay attention to the direction items are moving, instead of wishing something else were there.
