Billionaire Warren Buffett, widely considered the smartest investor on the planet and known for his modest lifestyle despite astronomical wealth, was recently asked the best advice he ever received. Surprisingly, it wasn’t about money, finances or wealth creation. It was about parenting. Here’s what Buffett said about the best advice he’s ever received:

The power of unconditional love. I mean, there is no power on earth like unconditional love. And I think that if you offered that to your child, I mean you’re 90 percent of the way home. There may be days when you don’t feel like it, it’s not uncritical love, that’s a different animal, but to know you can always come back, that is huge in life. That takes you a long, long way. And I would say that every parent out there that can extend that to their child at an early age, it’s going to make for a better human being. – Warren Buffett
