Explanatory. There can be no exceptions. I have never met effective, happy or successful people who would not be sensible. They are very responsible for their work and their lives. They act meaningfully, pursuing a specific goal. And most importantly, they know what they are talking about.

Curious. Effective people avoid assumptions. It used to be my biggest mistake. I was constantly making assumptions. One day one of my colleagues directly advised me to stop being so arrogant. And that's what I did. I decided to become curious instead. Effective people ask a lot of questions. This is how you can avoid assumptions.
