Now it's clear that in addition to knowing nothing about CBT, you also know nothing about what it takes to become a licensed therapist. My fiancé just became one, so I can help educate you: it goes far, far beyond textbook learning. After you get your Masters, you have to accumulate 3000 hours of supervised professional therapy under the guidance of another therapist who is licensed, and then after that you must pass an ethics exam and a clinical exam as well. Therapists are rigorously trained.
