I believe that "charismatic" isn't something you call yourself - It's something your audience / team / followers calls you.

In my experience charismatic people do tend to be extraordinarily passionate people.

So perhaps to become more charismatic - be more passionate.

First thing to remember is that you don't need to be a 'charismatic' leader to be successful.

I believe that when you speak from the heart about something you are passionate about and your goal is to help someone other than yourself (eg. employees, customers, community, etc...) your true charisma which we all possess will come to light.

I hope this helps

In simple language the word “Charismatic” means, “exercising a compelling charm which inspires devotion in others.” So how can you exercise this compelling charm? Well, it is simple. Just apply the appropriate leadership model to your company and become a charismatic leader. For example, you can apply Mintzberg’s Management Roles. These roles cover ten tasks and responsibilities that a manager may need to perform, which are divided up into three categories: interpersonal, informational, and decisional. Interpersonal roles include the figurehead, leader, and liaison. You may also apply Birkinshaw’s Four Dimensions of Management. This model highlights four dimensions that represent key management processes and practices.
