Like others, family was (is) the hardest obstacle. I live an hour from my immediate family, and hence don't see them as often as the rest of the people in my life. Therefore, it's frustrating when after being full time for nearly two years and everyone else in my life having made the transition totally fine, I still get the occasional "he" or "<old name>" from my family. It throws me off, since I don't hear incorrect pronouns at all anywhere else, then I go home and I have to continually be reminded of my past.
Besides that though, RLT (ie. life, at this point) has been dandy.
