In our business, as much as any other, nothing is given to us tomorrow. I'd challenge you to take in what's in front of you today, be grateful for the opportunity and make the most of it. It may result in a new business win, a promotion, helping someone else get promoted...who knows. But if you don't see what's in front of you, it might not be there tomorrow.
Here's an amazing film from Louie Schwartzberg at a TED conference on the concept of Gratitude. Truly worth ten minutes of your time.
