Would you rather work hard when you're young and retire early or live comfortably and retire when you're 60?

Would you rather: Become an entrepreneur, work hard, pour your heart into a business, give up your life in your 20s, and hopefully retire wealthy around 30 OR work comfortably for the next 40 years, have stability, enjoy the free time you have with family and friends on vacations/weekends/nights, and hope to retire with enough money to live on until you die? I'm interested in the opinions of everyone.
