In a recent interview with The Huffington Post, the Oracle of Omaha shares some honest (albeit unexpected) wisdom.

After decades of providing business tips and advice to others, Buffett was asked what the best piece of advice he’d ever received was. Surprisingly, the answer had nothing to do with business … at least not directly.

Buffett cited his father, who he credits with teaching him the power of “unconditional love.”

“The biggest lesson I got is the power of unconditional love,” Buffett explained. “If you offer that to your child you’re 90% of the way home. If every parent out there can extend that to their child at a very young age – it’s going to make for a better human being.”

Buffett couldn’t recall exactly what the worst advice he’d ever received was. But he did share this gem of wisdom he once received from close friend (and one-time business partner) Tom Murphy:

“Never forget, you can tell a guy to go to hell tomorrow … You don’t give up the right. So just keep your mouth shut today and see if you feel the same way tomorrow.”
