What energizes you more: learning something or teaching something?
Life doesn’t feel right if I’m not learning stuff regularly. New ideas open possibilities and give me a sense of opportunity.
Teaching is important to me, too, though. It requires me to really understand what I’ve learned — it’s sort of an advanced form of learning, really. It gives me much more confidence in a subject. (It also takes confidence.)
Teaching somebody something can be really fulfilling, too. I’m lucky to be able to do it regularly as a parent.
