Your first step to becoming a better human should be to take care of the vessel you've been privileged to use while in this realm.

Doing so will make you more resilient to the world's stressors, happier, more confident, more attractive, and more persuasive.

Look at the physicality and health of your peers, of the general population. It hardly takes any effort to surpass 99% of them.

Maximize meat, fish, and eggs.

Minimize fruits, vegetables, and process garbage.

Lift heavy shit.

It's that easy.
