The video below was filmed at an Intervarsity leadership conference. If you're not familiar with IV, they're a fantastic college campus ministry which operates on almost every campus in the US. I've recently been offered the honor of being a guest-writer for their blog, and I'm told one of my articles will be published later this month.
In the meantime, please watch this sermon. It's almost 40 minutes, so I suggest pulling up a comfy chair.
The thing about disappointments and failures is that they don't last forever.
