If you are already out, good for you. You have paved the way for other transgender women and men in the future.
If you have not had the chance to live as your authentic gender self, don't give up. Many times the world can change quickly and you will have a chance. I am an example of that.
Another important consideration to not forget is even though you are not out, don't forget to support others who are. Many times you can do it at the ballot box.
In the mean time, appreciate your day!
