The Endeavour: Whether to delegate

Managing energy is more important than managing time. Energy is what gets things done, and time is only a crude surrogate for energy. Instead of only looking at what you could earn per hour versus what you could hire someone else for per hour, consider the energy it would take you to do something versus the energy it would free to delegate it. If something saps your energy and puts you in a bad mood, delegate it even if you have to pay someone more to do it than it would cost you do to yourself. And if something gives you energy, maybe you should do it yourself even if someone else could do it cheaper.
