In the AI era, a person’s ultimate moat is “energy.” Don’t trade money by burning out your body—boost your efficiency per unit of time by keeping a regular schedule.

Once you don’t sleep well and your body is in a sub-health, fatigued state, not only will your judgment and attention drop off a cliff, but you’ll also be more likely to get sick.
Go to bed early and wake up early + keep exercising—save your life and, too, bring in wealth.
