Most executives believe that their hard work — and only their hard work — got them to the position that they now sit. All the hours, all the meetings, the handshaking, the brainstorming, the late-night dinners brought them to the exact spot that they are in at this moment. Sorry to burst your bubble. But there's more.

Your colleagues. Many people that have worked under you, the peers beside you, and yes, the many bosses above you that helped you get to the spot you're presently in.

Time to begin thanking them. Take the next 30 days and each day, reach out to one of them with a 5 minute phone call and let them know how important they are to you. That's leadership.

5 minutes - it will make someone's day.
