Worry will never solve tomorrow's problems. It will only take energy away from today.
Every time you say yes to something you don’t want to do, this will happen: you will resent people, you will do a bad job, you will have less energy for the things you were doing a good job on, you will make less money, and yet another small percentage of your life will be used up, burned up, a smoke signal to the future saying, “I did it again.
I'm a big believer in minimalism. Not materialist minimalism although that's part of it but time and energy minimalism. The body is given only so much energy a day.
