Sometimes it's necessary and even beneficial to sleep less.
If I'm playing a gig until 2 in the morning then get offered $700 to play the starting line of a marathon 5 hours later then sleep can wait. If I need to work a straight 23 hours to earn $1,500 at a wedding sleep can wait.
With that said though, the real grind is maintaining the simple day-to-day activities that make those hours and paydays possible in the first place. Staying motivated and attentive to these tasks requires adequate sleep, food leisure, meditation, and exercise. I never pull an all-nighter without knowing what the goal and the endgame is.
