The King of Wands at his best is someone who is charismatic, creative and bold. Perhaps this charming man has come into your life, or is already someone you know. Perhaps he is someone involved with your work or in your love life.
If this King does not represent someone in your life, he is asking you to adopt some of his character traits.
A lot of people have a set idea of what charisma looks like and who possesses it.
There was a great article in the New York Times by the poet K'naan. In it he talks about a fox who gets so enamored by how shamans walk, that the fox spent a considerable amount of time trying to walk like they did, and in doing the so eventually forgot how a fox walks.
The moral of this story is to walk your own authentic walk and follow your own authentic path, seeking out what deeply resonates with you. When you walk your own walk, you have your own type of charisma that inspires others to follow your example.
You do not need to be an extrovert for this. Ghandi had tons of charisma and he was an introvert. So was Albert Einstein. You don't need to be a genius either, though. You can just be yourself.
When you are yourself, and at ease with that, others associate feeling at ease around you, and thus you are charismatic in your true way.
The King of Wands is also a leader.
So if you have the inclination to lead, be bold and take the reins, especially if you find yourself in a situation where you have ideas that can help foster something that helps others.
Also, if you aren't quite ready to lead yet, but hope to do so in the future, then do all you can to prepare for that eventuality. Believe in yourself.
