A week ago, President Obama was on 60 Minutes and was asked what makes a President great. Obama replied, “Persistence.” Which really got me thinking about my own life. Everything great in my life has been the result of persistence. Over the last couple of months I lost the persistence that I needed to succeed. I felt myself starting to complain—not to others, but to myself.

The main thing that changed is I lost a little bit of my persistence. In order to succeed in whatever you do, you need to become doggedly persistent. Yes, you will annoy people. Yes, you will even piss some people off. But if you’re not annoying at least some people, you’re not trying.
