David Goggins said it right:
“Many people wake up with dread or doubt day after day. They dread their workouts, their class load, or their job. Maybe they have a test or presentation that makes them nervous, or they know that the day's workout will hurt. While they linger in bed, they tune into their soft, forgiving self-talk, which doesn't make it any easier to get up and moving. Most people rise up eventually, but they remain in a daze for hours because they aren't fully engaged with their lives. Their self-talk has made them numb to the moment, and they sleepwalk through half the day before they finally perk the fuck up.”
