My life's struggle besides keeping my transgenderism secret was trying to make it to the NHL as a goaltender. I played with guys who did make it and I got as far as University hockey here in Canada. I had often wondered what I was going to do about being transgendered if I did make it. I decided to try and make it first then deal with my issue afterwards. As it turned out I didn't have to deal with it.
I thought I read about someone in one of the TGG forums (News probably) who made it as a muscian and then transitioned. She had to struggle to try to get back to where she was as a male musician.
I would look into these types of examples first before making a decision you may regret later.
