This is alll from 21 Indispensable Qualities of a Leader

To improve your charisma, do the following: Change your focus. Observe your interaction with people during the next few days. As you talk to others, determine how much of your conversation is concentrated on yourself. Determine to tip the balance in favor of focusing on others. Play the first impression game. Try an experiment. The next time you meet someone for the first time, try your best to make a good impression. Learn the person’s name. Focus on his interests. Be positive. And most important, treat him as a “10.” If you can do this for a day, you can do it every day. And that will increase your charisma overnight. Share yourself. Make it your long-term goal to share your resources with others. Think about how you can add value to five people in your life this year. They can be family members, colleagues, employees, or friends. Provide resources to help them grow personally and professionally, and share your personal journey with them.

I personally thinkgs this sounds awesome and will be trying it out!
