As you are looking for a good therapist, be sure to express your own beliefs and values to them. You should strive to be yourself in therapy, and be as honest and upfront as possible. Ideally, your therapist will share a similar worldview, or is willing to provide objective, unbiased information for you so that you may make your own informed opinions. At the same time, you should be ready to hear some things you don't necessarily want to hear, and be willing to consider the suggestions that are given.
Your first session with a therapist does not mean you must continue to see that person. You are free to discontinue therapy at any time without consequence - regardless of whether that is after the first, second, tenth, or any other session. Meet a variety of therapists and explore their different personalities and styles before deciding on who to continue therapy with. The therapeutic relationship is the most important factor that will influence the success of the counselling experience.
