In his book Antifragile, Nassim Taleb defines a modern Stoic as “someone who transforms fear into prudence, pain into information, mistakes into initiation, and desires into undertaking.”
Fear into prudence: Don’t be overtaken by your fears. Don’t forget them either though. Be cautious.
Pain into information: Understand what caused the pain and don’t repeat it. Learn from your mistakes.
Mistakes into initiation: Don’t be discouraged by mistakes. Use them to your advantage. Now you know what not to do.
Desires into undertaking: Don’t just be a dreamer. Be a doer. Don’t be precious. Be proactive.
