For me, unlikely. By the time I get surgery, I will likely be in my mid to late 30s. I have missed my childhood, teens, and 20s. I tried to come out and transition when I was a 14. I told the school counselor and he called my parents and told them I was mentally ill (technically "true" under the DSM of that day) and needed serious help to make me realize I was not a girl. I look back and wish I had been accepted like some kids (e.g. Jazz Jennings) are today and had their opportunities. How life would have been different if I had only been able to live as who I really am when I was younger. OTOH, had I gone to school as a girl back then, I would probably have been beaten sh**less and the school would have sided with the bullies.
[EDIT] That said, it is absolutely possible to accept yourself and be happy.
