The thing about life is that it's never the way you think it's going to be.
The best advice I can give is to stay humble and work hard.
Listen to everyone in your company and figure out ways to get them talking. The folks on the front lines—the ones who actually talk to the customer—are the only ones who really know what's going on out there. You'd better find out what they know.
The only way to be happy is to love what you do.
