My productivity life hack is not having any dependents. I have no children, no pets, and no plants.
Having children is optional, and in many ways, can reasonably be said to ruin one’s life. They’re also expensive and terrible for the environment.
Working around an opt-in kneecapping seems silly to me. Just don’t reproduce and you won’t have to figure out life hacks because your children’s existence is incompatible with productivity in areas other than raising children.
