And he was a whole lot more financially successful too!
I just read Mark's book on Kindle for something like $2 - How to Win at the Sport of Business: If I Can Do It, You Can Do It - and although a little short, I enjoyed reading about his feisty background.
Here's the money quote:
In sports, the only thing a player can truly control is effort. The same applies to business. The only thing any entrepreneur, salesperson or anyone in any position can control is their effort.
I had to kick myself in the ass and recommit to getting up early, staying up late and consuming everything I possibly could to get an edge. I had to commit to making the effort to be as productive as I possibly could. It meant making sure that every hour of the day that I could contact a customer was selling time, and when customers were sleeping, I was doing things that prepared me to make more sales and to make my company better.
And finally, I had to make sure I wasn’t lying to myself about how hard I was working. It would have been easy to judge effort by how many hours a day passed while I was at work. That’s the worst way to measure effort.
Effort is measured by setting goals and getting results. What did I need to do to close this account? What did I need to do to win this segment of business? What did I need to do to understand this technology or that business better than anyone? What did I need to do to find an edge? Where does that edge come from, and how was I going to get there?
The one requirement for success in our business lives is effort. Either you make the commitment to get results or you don't.
