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

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.

Reaching your potential is a disciplined process. Like losing weight or getting in shape - there is no final destination and it requires you to dust off atrophied muscles. You have to work at it. If you do, I think you will dramatically improve your leadership.

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.
