Whoever thinks this is good advice has an extremely easy life. Most people have literally no slack time at all. You're supposed to execute your great plans in the 1 hour per day you have after work, commute, taking care of family, and occasionally taking care of yourself? The hour in which you are deeply exhausted? If that doesn't sound like you, congratulations: you have an easy life.
So the real advice is the same as all life advice under the hood: just be born into privilege.
