Aim for the best, not to be right
Once you believe that you are right the world starts to shrink around you.
People that believe themselves right tend to stop asking questions, searching for alternatives, or listening to others.
It is often better to aspire for the best; the best explanation, the best answer, the best course of action, the best decision.
Searching for best means that you have room to grow. Right tends to change with time or context anyway.
