I am working on the try it and see, and take small steps.
People can de-transition if it feels wrong later, although only a small percentage tend to de-transition.
Most people who get to the stage where they transition have spent some time considering it before they reveal themselves to the wider world.
Personally I am taking small steps to keep my dysphoria in-check, removing body hair, shaping eye-brows, clothing, telling people, changing my title and pronouns, getting my ears pierced. No medical intervention yet, unless I need it. Next may be (semi-permanent?) facial hair removal.
