Charismatic power increase your confidence and it boost every thing which makes you stronger than your expectations, We are human beings and we cannot do any thing which is bad for us. Take risks and overcome your weak points. Just focus on yourself and avoid shyness in your mind. According to my experience, John Wick, Daniel Craig, and Cillian Murphy are the best examples of charismatic power.
Christian Bale is also real life example of charismatic quality. Do some work-outs, save your time, ready for battle and war, build your self-esteem and roar like The Lion. Daily preparation is good for particular tasks.
