Answer:
It's most important to have knowledge about a subject so you can help others understand it and so you have a better understanding of it as well.

Passion does not equate to skill or talent. The simple fact that we are passionate about something does not mean we can succeed at it. Skill is required regardless of passion. It does not matter how much we love something, there are no shortcuts.
I believe that the best answer for this question would be sanguine. People who fall under the category of the sanguine temperament tend to be lively, pleasure-seeking, talkative, and highly social. They can easily fall in love and may be flighty and forgetful.

Hope this helps.
