O, The Oprah Magazine, in partnership with Zappos.com, is going on a kindness mission to spread the love and make the world a friendlier place. Each month, we'll be giving you a brand new kindness challenge. This month's challenge—Give Great Advice!

A great piece of advice is priceless. This month, O Magazine is asking readers to share the best advice they have ever received as a way to pay it forward. Tag the friend/s who gave you the golden piece of advice. In the Random Acts of O tab, there are also great tips on how to give great advice to a friend.

So go ahead and share the wealth of wisdom! It’s contagious.
