I came to reach a similar conclusion - but irrespective of the outcome of my transition - so I have started to make small steps in freelance activism/lobbying. Given peculiarities of my professional duties, I often find myself in the situation where I can drop a word or two (and people tend to listen to me - at least for now..) and try to shift the balance or generate ideas, which migh result in some positive developments for the whole LGBT group.
Several months ago I read a post in our local LGBT board - on the subsection which was dedicated to transgender people were sharing their dreams and wishes. And one particular post struck me very deep - that person said that she is yet to meet a transsexual woman (well, she said "tgirl" but nevermind...) who was proud being one and was confident in all areas of life. I thought that this was something worth to aspire for during and past my transition 🙂
