This is interesting, if this was a checklist, I would check all 9 items. My biggest learning, there are no sure things in life. Regardless of what you do, there are always going to be setbacks. The setbacks, they are good, they are a source of energy, that propels one forward. They force change. Just like water in a lake has a lot of energy but when it falls over in a water fall we start to observe that force. Change, constant change converts raw energy, your potential into something meaningful and worthwhile. Keep changing, keep morphing.
