Found on Cosmos
The Latin aphorism, ars longa, vita brevis , describes exactly this: skilfulness takes time and life is short. In order to become anything, you must eliminate everything else — life is about choosing your sacrifices, you don’t get to not make any, but you get to choose which ones.

Rust Cohle: Life's barely long enough to get good at one thing. So be careful what you get good at.
Your decisions about allocating your personal time, energy, and talent ultimately shape your life’s strategy.

Do not make barely positive-value bets with your life!
