There are different forms of rest, and getting the wrong kind can be as bad as getting none.
No one can go go go forever. You need to recharge, but “recharging” doesn’t just mean sleeping. If you don’t believe me, picture a life where you get nine hours of sleep every night, but you spend the other 15 hours each day working – every day. Do you imagine that you’ll feel rested? Will you be able to maintain it?
Satisfaction, engaging other parts of your brain, leisure and enjoyment, productivity on other priorities – these are all ways “resting” and getting back the energy you need to be able to give to the world in exchange for its bounties. Don’t neglect them.
