In Your 20s, There Are No Sunken Costs

In your 20s, you'll experience the illusion of sunken costs because your mind only accounts for the time being alive. Be in the top 10% of your profession or industry, and you'll probably be seen as successful. Don't be afraid to say fuck it and start something else. Quit that toxic relationship. Drop out of university if you realize this isn't for you. Life is longer when you add chapters to it.
