Some old articles / statements are worth rereading. Here is one of my favorites:

What is Edge ?

The edge is knowing that you can fail and learn from it, and just get back up and in the game.
The edge is knowing that people think your crazy, and they are right, but you don’t care what they think.
The edge is knowing how to blow off steam a couple times a week, just so you can refocus on business
The edge is knowing that you are getting to your goals and treating people right along the way because as good as you can be, you are so focused that you need regular people around you to balance you and help you.
The edge is being able to call out someone on a business issue because you know you have done your homework.
The edge is recognizing when you are wrong, and working harder to make sure it doesn’t happen again.
The edge is being able to drill down and identify issues and problems and solve them before anyone knows they are there.
The edge is knowing that while everyone else is talking about nonsense like the will to win, and how they know they can be successful, you are preparing yourself to compete so that you will be successful.

That’s what makes business such an amazing sport. Everyone plays it. Everyone talks about how good they are or will be at it. Just a small percentage are.
