You do not stop learning once you graduate – hopefully. Each day presents something you didn't know before. You must be open to the knowledge, not confident in the mistaken belief that you already know everything. Even a day you take off to relax can hold lessons. A highly successful friend of mine takes one day a week off as her “sharpen the saw” day. It is the day she studies her own business. She says: “that day is to rebalance my energy, increase my mental clarity, unplug from the technology demons and discover my personal power. “
You continue learning as long as you are alive. If you stop learning, notice if someone is throwing dirt on you.
