Know what you’re not good at. I find that most people know what their strengths are, but most people – especially Gen Yers – don’t know what their weaknesses are. Honestly determine what you’re not good at, and hire or delegate to those weaknesses. This will help you focus on your strength areas.
Know what not to do. Just as important as what you decide to do is what you decide not to do.
Find a focus and stick with it. A major failure of leaders and managers is that they are trying to focus on too much. Successful people are focused like lasers on one thing.
