Calpernia Addams <http://www.calpernia.com/> notes in a thoughtful essay full of advice for young people considering a gender transition:
Transition is never perfect, never easy and never finished. But it does get better, it does easier and it does recede into the background as time goes by.
[…] Focus on your dream, visualize yourself as a beautiful, happy woman living in her own place, with her own car and a good job where she is so valued and essential due to her skills that they would have no problem accepting her past if it should ever come to light.
