Successful leaders also do a lot of reading about how to become even more effective.
A book a colleague recommended to me is one I recommend to you. It's called “Execution — The Discipline Of Getting Things Done.”
Particularly powerful are the seven behaviors of strong leaders that the book mentions on page 57:
1. Know your people and your business.
2. Insist on realism.
3. Set clear goals and priorities.
4. Follow through.
5. Reward the doers.
6. Expand people's capabilities.
7. Know yourself.
You'll find posts on this Blog about some of these behaviors, but for expanded thoughts about each, give the book a read.
