Warren Buffett didn’t slow down when he turned 65. Or 70. Or 75. Today he’s 80—15 years beyond the generally accepted retirement age… and he’s still going strong. Now the question is… does he love his work because he is the third-richest man in the world? Or did he become that rich because he loves his work? Make sure the work you do is the work you are passionate about… it’s the difference between strapping a rocket or an anvil to your back.
