Here are my takeaways on the answer to that question from the Harvard Business Review articles:
1. Find your strengths and use them. Focusing on weaknesses doesn't necessarily help and it can hurt.
2. Be able to answer this question: Why should anyone be led by you?
3. Becoming the boss doesn't mean your in control...or anything else you thought it might.
4. Leadership is not charisma but faith combined with reason.
5. Being a good boss in a bad economy is especially hard. It helps if you provide as much predictability, understanding and control as possible and it makes an incredible difference for the good if you can do that with compassion.
It's amazing what you can learn when you're paying attention, even when you're not in class!
