I need to control my mind from making up thoughts and assumptions that most of the time 80% untrue but takes up 100% of my energy and confidence worrying, well, over something which is not even there yet and cracking heads answering "what-if" situations.
It is sometimes good to anticipate things that might come so that you are mentally prepared. For example, my friend asked me to think of the most painful experience before my 5-hour dental surgery last year so that I would not feel much pain if the pain from the cut in the mouth is lesser than what I have expected.
Well, my goal for now is not to make any assumptions. Actively seek for confirmation and give feedbacks honestly.
