The 10 Greatest Challenges Every Human Must Endure to Experience Self-Actualization
Fantastic list from @BillBergeman, I don't have 10 to add though.
1. Know when to keep quiet
2. Recognize when you might be wrong
3. Able to assess in real time when you'll be better off favoring the long term over the short term
Play the long game.
4. Recognize factors that might impede your judgment
Fatigue, anger or sadness.
5. Recognize when less is more
Relevant on countless fronts.
Good summary of this entire list.
