Your question is a very familiar one! Two thoughts which usually come to my mind are either “how much of what I am experiencing is of my own doing?” or “everything seems to be getting so much for me that I have no choice but to take it as it comes!”. I usually sway between “what have I done right/wrong?” and resignation/hope. Even though I do not claim to be free from the “swinging forces” of human emotions, I do believe and have experienced that a lot depends on fundamental decisions. The potentials of a situation lies in how I add to it through my reactions and my fundamental decisions are enhanced by any situation I meet in life.
