I'm not gonna speak for anybody else on the matter, but objectively I've benefited from being trans in many ways. When I finally laid off the denial and questioned why I 'should' just accept being stuck as a male, I also started questioning and rejecting everything else. Granted, that led to a turbulent few years that I bear quite a few scars from, but I believe I'm a better person for it - I may have run away from my problems, but my sense of the world, of social justice, my understanding of people all bloomed. Now that I AM finally deaing with my GID, I find that I have a much stronger sense of purpose, of my own strengths and weaknesses, of my conceits and short-comings than many people quite a bit older than me seem to have.
Of course, I would really have liked for all this learning and growth to have happened when I was nine so I could have transitioned then, or better yet have been born natal and learned these things in some other, less painful way, but I suppose 29 is still young, and I wouldn't trade what I have gained from my CFP (confused, frustrated and pissed-off) period.
