Manage yourself and orchestrate others to get what you want.

You need to have the right people in the right positions. But before you decide, you must learn more about how different personalities work with each other and what their work ethics are. You can do this through psychometric tests, which are much better than standard job interviews.

Understanding this subject well will help you understand why some people just don’t do their jobs well or why people don’t cooperate well. This is essential to have a team of people that will accomplish your goals.

1. When you hire people, use psychometric tests—they are far more important than standard job interviews.
   The popular ones are the Myers-Briggs Type Indicator, Workplace Personality Inventory, Team Dimensions Profile, Stratified Systems Theory, and Big Five.

2. Getting the right people in the right roles is the key to succeeding at whatever you chose to accomplish.
   In both your private and work life, you need people who will be complementary to you, so you have the best mix of attributes.

3. Manage yourself and orchestrate others.
   Your team is like an orchestra. You don’t have to know how to play the piano, but you must know what’s necessary about it. When you know all the instruments that you have at your disposal, and how they play with each other, you can decide how to make it better—for example, who must be fired, who must be replaced, or whom you should hire.
