For nutrition, the game-changer according to the Pareto principle is cutting out ultra-processed foods. These are the items produced in factories, laden with chemicals, inflammatory oils, and excessive sugars, all of which severely compromise your immune system.

Meaningful and moral are different in an interesting sense; something can be meaningful, and yet be morally terrible. Adolf Eichmann was clearly engaged in what he thought was a meaningful pursuit, perhaps he was even in a state of flow, thinking that what he was doing was 'good' – even though he was the architect of the death of millions.

It's about finding the right balance between being bold, patient, and persistent. For me, it's about not thinking it's crazy to reach out to an Oscar winner or a billionaire, but realizing it takes patience and time.

As war ravaged Liberia, I realized it is women who bear the greatest burden in prolonged conflicts. We began organizing Christian and Muslim women to demonstrate together, launching protests and a sex strike to help oust Charles Taylor.

Look at it this way, there's practically no friction to sign-up to DoorDash as a dasher. If you have a car or bike, you can start dashing in hours, and earning money.
