Some of you may know that some of my favorite books are actual biographies – most specifically of billionaires. I’ve learned so much by reading about their actual experiences – the wins and fails – and today, I’m going to share my top three lessons I’ve learned from billionaires Warren Buffett, Elon Musk and Richard Branson.

Lesson No. 1 – In order to get some of your time back and get more done, give yourself permission to say NO to more things.

“The difference between successful people and really successful people is that the really successful people say no to almost everything.” – Warren Buffett

Time is our most valuable asset and it should be invested in the same fashion.

“Invest your time in all the right places.”

By saying no, you’re gaining back both time and energy, and you’re able to get laser-focused on the areas that need it. Even if it’s gaining back one hour a day, that’s getting back just over 15 days in one year! Just think of what you could do with that time with your family and friends.

Lesson No. 2 – Go all in!

“No matter what you’ve done in the past, you’ve got to check your ego at the door and be willing to ask for help.”

Elon Musk is the perfect example of this as he is so passionate about his dreams/businesses. So much so that he nearly went broke multiple times trying to achieve them. Needless to say, he now has billion-dollar companies and is himself a billionaire.

Lesson No. 3 – Make an impact while living a fun and well-rounded life.

“A life worth living is a life full of well-rounded memories and impact.”

Make it a rich, fulfilling and meaningful life without apologizing. Don’t make it a life about just your family… or just your business… or just your adventures… Do it all, because how you do anything is how you do everything.

These are three of the lessons I tap into when focusing on how I want to live my life. And no matter how you define success, I’m guessing these three billionaires will pass the test. After all, in my opinion, they’re all living my motto: “When good people make good money, they do great things.”
