The mental toughness, discipline, and higher energy levels that come with exercise are more important to me than physical appearance or living longer, and at this point almost anything else in life.

Wake up at 4am, run hill repeats for miles and then go into work. I guarantee no incident or colleague will trigger a stress response. You will feel as cool as a cucumber and when an urgent issue does come up you will handle it with absolute mental clarity. That afternoon drowsiness will also not hit you at all, counterintuitive right?

By 9pm you will fall asleep no matter what happened that day.

This kind of work gives you an edge on everyone. You look at things and say, “shit this is easy compared to what I did this morning” and you will feel mentally fresh.
