[W]e have one reservoir of willpower. It’s a highly limited resource, and it gets depleted by every act that requires its use.
Tony Schwartz, proponent of maintaining your energy levels for sustainable productivity, offers a Master Plan for Taking Control of Your Life back from all those temptations that ultimately deplete your tank of willpower.
His two tips related to eating and sleeping are great reminders to attend to your physical health in order to give your best during the day:
4. Sleep as much as you must to feel fully rested.

6. Eat energy rich foods in small doses at frequent intervals.
Schwartz recommends refueling at least every three hours. Skip the mocha choco latte yeah yeah and donuts, and snack on lean proteins and complex carbohydrates for longer lasting energy boosts. Here are some helpful meal and snack ideas.
