Ask HN: What's Your Biggest Regret?
everyone loses 10 years to something, somewhere along the line
That's a fallacy. You didn't so much "lose" 10 years, it just took 10 years to come to an understanding about a meaningful part of your life. And maybe you really needed all that time to arrive there.
Whatever your goal is, try to stop having 0% days.
You don't need to have 100% days, Just avoid having 0% days.
