Execution is a systematic process of rigorously discussing hows and whats, tenaciously following through, and ensuring accountability.
If you don't have the best people you hurt everyone.
Complexity has nothing to do with intelligence, simplicity does.
Execution is the job of the business leader.
Self-awareness gives you the capacity to learn from your mistakes as well as your successes. It enables you to keep growing.
I am convinced that nothing we do is more important than hiring and developing people. At the end of the day you bet on people, not on strategies.
