I'm like everybody else. I measure my days by to-do lists. I hear a mental voice say "move!" when I curl up in a lounge chair for too long. I worry about "wasted" time.
But this isn't a healthy way to live. Finishing a to-do list is important, but getting enough sleep each night is more important. There was a time in my youth when I limped by on very little sleep. Now I understand that's just a goofy way to live. Your health is like a checking account. You can write big checks against it for only so long before it gets overdrawn.
Your body needs sleep to recover and replenish itself. Your mind also needs rest from constant activity and confusion. Some people meditate. Some read. Some garden. Some do yoga. Whatever clears your mind and refreshes you will work.
Sometimes to go faster, you need to slow down.
