You might have limitless purpose and still not be motivated because you need the energy. Somebody who is exhausted, they're not going to feel motivated to read, to work out, to meditate, to be able to make those 10 sales calls, to do those presentations, to do difficult things, to get out their comfort zone. So you need energy because exhaustion will make a coward out of any of us. And so what are 1, 2, or 3 things you could do to generate more energy? Maybe it's to go to bed by a certain time. Maybe it's to get direct sunlight first thing in the morning. Maybe it's to eat those brain foods. Maybe it's to do some deep breathing. Maybe it's to hydrate yourself to have energy.
