Your fixation on improving or learning something in life should go no further than developing to a high degree your ability to experience your experience more fully. You have the perfect playground for developing such skills as well. It’s right here right now without the intellectualization of previous experiences or the confusion of imagined future experiences that do not exist in reality.
In other words, you love what is, and life fills in all the blanks, or you play multiple-choice and live a life where your carefully thought-out, well-reasoned, and meticulously committed to memory guesses are wrong. You won’t fail in either case, but you might experience less stress and much more fun. Just sayin’.
Living by the book or just living. It’s not much of a choice if you don’t think about it, but it’s a monster if you do, So don’t.
