The better strategy is to focus on strengths and surround yourself with people who can complement your skills. However, you have to first do the analysis.

There's a step that leaders need to take; they've got to understand themselves.

One reason leaders don't delegate is they haven't been sufficiently clear with the team regarding their vision and key priorities - so that the team understands where the firm is going. If everyone is on the same page, it's a lot easier to delegate effectively.

Every person I meet is struggling with how to understand themselves and reach their full potential. No one has it fully figured out. It is a life long struggle - -there isn't a precise destination or arrival.

There is usually a clock in our heads regarding decisions we make and the course of our lives. Sometimes this clock is helpful in that it get us to move rather than put off key actions. Other times, it creates us false sense of urgency that can cause us to overreact, lost patience and make poor decisions. In raising this issue in my book, I want people to be aware of the clock in their heads and question whether that clock is helping or hindering the quality of each particular decision.

Why do leaders fail? Isolation and inability to learn. They are afraid to express doubt, admit vulnerability or seek advice from subordinates. Leaders must actively work to seek feedback and a reality check. They must be open to asking questions and framing issues. As the world becomes more complex and global, the risk of isolation becomes greater. The need for leaders to be open to learning becomes greater. Great leaders will need to ask the right questions and balance inquiry with advocacy.

The vision must be realistic - it has to be based on clear distinctive competencies. Again, what would the world lose if you didn't exist? A vision is very powerful because it gives you a basis to judge every action you take. Every action should be viewed through the prism of whether it furthers the vision.
