In order to be successful in real estate, you must have enthusiasm. Successful buyers and sellers typically share their agent's enthusiasm. I hope you get excited about real estate too. It certainly helps with your outlook and the outcome. Here's a quote I like:

Every memorable act in the history of the world is a triumph of enthusiasm. Nothing great was ever achieved without it, because it gives any challenge or any occupation, no matter how frightening or difficult, a new meaning. Without enthusiasm you are doomed to a life of mediocrity, but with it you can accomplish miracles.
