Inspirational leaders need to have a winning mentality in order to inspire respect. It is hard to trust in the leadership of someone who is half-hearted about their purpose, or only sporadic in focus or enthusiasm.
Motivation is everything. You can do the work of two people, but you can't be two people. Instead, you have to inspire the next guy down the line and get him to inspire his people.
I was raised to give back. I was born to immigrant parents and was fortunate to become successful at an early age. I've always felt a strong sense of national service to my country, and I may have been able to provide leadership in the political arena. I don't regret the decision not to enter politics, I just wonder sometimes if I could have changed anything.
