I struggle with this notion almost daily. I am not fully out to everyone yet so therefore I still present a majority of the time as male, even though I feel and act quite abit in feminine mode and roles. I am also pre-HRT for at least a few more weeks, but I know in my mind that I am a girl and will become the woman I desire to be in the next couple of years.
You just need to take each day as it comes, be yourself, and let yourself grow into who you desire to become. We are all different and there is no one correct template that you have to model yourself after. Society has placed a lot of preconcieved idea's in our heads about what men and women are suppose to be like, but I know a lot of people (non-TG/TS) of both genders that have significantly crossed those lines. So, I honestly believe that you have to be who you want to be. Most important thing is to be happy with who you are and to have a positive outlook.
Attitude is of the utmost importance & be true to yourself.
