One day, I hope to be entirely open about who I am. I have no desire to make a political statement. I do not want to 'fight' for trans rights. What I hope to do is increase awareness of trans folks and, thereby, play a small role in furthering acceptance.
I have always been interested in helping people. Over the years, I have come up with various excuses for not following dreams to become:
1. a minister (as a teen and again in my 30s) - applied to seminaries more than once. Accepted but never went.
2. a college professor (throughout my undergraduate years and while going through my first stint at grad school) - offered college instructor position when I got my degree, I turned it down because I thought it would not lead any place.
3. a physician (as a college student and again in my early 30s) - offered interviews to medical school while a student,which I turned down - later was ready to apply again and set to go. Ex-wife, however, said she could not handle this - said she would give me divorce instead - I chose to remain married.
4. a professional musician (high school and college) - music helps people, too

- when I started college, I was a music major and continued advanced piano and organ lessons
5. a clinical psychologist (late 30s, early 40s) - investigated this heavily, opted instead to work for grad degree in chemistry - seemed like a more promising way to a secure future
Instead of following my passions, I took what seemed to be more sensible paths. I think my decisions are rooted in my family history. Duh!
For one thing, my father always said we were poor. When I was a young child, my father worked three jobs to keep a roof over our heads and food on the table. After doing this for several years, his doctor told him he needed to stop or he would die. During my teen years, he at times held part time jobs to supplement his full time income.
I have written that money has never been my prime motivator. This is true. I still prefer to earn enough so I do not wind up having to work like my father did.
When I transitioned on the job, I was surprised to receive about 40 emails of support. More than one said I was helping other people by being so open. Many months ago, I probably wrote about just how open I was at that time. Of course, there was a company-wide announcement. The HR folks asked if I would also provide a lot more information about me and trans folks. I did and this was distributed.
My 'supporters' at the office back then may have been exactly right on one thing. They said I was doing enough to increase awareness and acceptance by living openly. Someday I hope to do more.
Since then, several people have suggested I travel around the country giving talks on my experiences and also, perhaps, motivational presentations. It's tough making a living this way! Besides, this is something you have to develop over time to create demand. There are many other people doing the same thing.
Someday, though, I want to get going on this. It will mean being very open about who I am.
My European trans woman friend is an inspiration in this regard. She is rather well known in some circles. She is also very open about her transsexuality.
I want to be open with people who become friends, too. Just last week, after a lot of thought, I told someone who had no clue exactly who I am. Meaning my somewhat unusual life history. I was confident he would take the news well and he did. It wasn't a big deal at all.
I have no family, so there is no one to be concerned about other than myself. My situation is different than some other folks who transition.
None of this means I am prepared to make a general announcement at the office. I am not and do not intend to. There will be no "Hey everyone, I'm a transsexual woman!"

Besides, this is the company where this is a non-issue.
Still, life can be lonely if you have to hide a major part of your personal history from everyone.
