There are many ways to use your intuition. The most basic way is to learn how to use your "gut feeling" as a life guidance tool. It is easy to not listen and/or listen to others before listening to your own intuition. But - then one ends up on someone else's plan for life by not listening to what is best for yourself.
Being comfortable with using your intuition means that you are being confident with yourself. Knowing the direction you want head, and following your instinct in getting to your goal and how to best achieve your goal.
