If I see things in terms of what I want to do and be in life, not regarding gender, my options are pretty limited...
I've for a long time wanted to be a businessperson, wanted to be involved in big things, be able to know big people, have lots of connections, etc...
My gender issues had derailed that. I'm age 32.
If I see things from that perspective, my options are pretty limited. Business is one of the more conservative fields. Your dealing with middle and upper class people, as well as a wide range of other people, and trust and respect are important. If you appear as weird or strange, it will severely hurt your chances in this field.
Thus seeing it from that perspective, my options are pretty limited. Either I make it as a woman (even if I have to lie about my past, or my own issues), or I have to stuff it all and pretend to be a regular male (good luck in how long that would last.)
Otherwise I have to live with a life of regret in terms of the stuff that I wanted to do in life.
This is why I don't believe this BS about being yourself. You have to make yourself, not be yourself. Unless you either relegate yourself to the arts or to the more liberal ends of society, or just happen to be a genetic female, you don't really have the choice to live as non-binary IMO.
Even then, how would cis-women accept you in their circles if you don't firmly say that you identify as a woman, at the least? (once again, exceptions for genetic females.) And that is if you acknowledge that you are trans.
I don't want to live a life stuck in a minority position. Why should my life be limited by my gender / expression / sexual orientation?
