The mission you’re on, the pursuit you’re after, the dream you have, the vision you see can’t be fulfilled through diluted attention, fractured time, or average effort. Every day is a test of your discipline.
You can direct your attention to a thousand other things, including all the things you might falsely believe are stopping you.
You can use your time to wait or relax or complain or entertain yourself.
You can put in little or no effort, or intense effort that is simply too brief.
