I'm probably about the same age as you, and so far in my life, I moved lived in twelve different houses/apartments, in six different cities and three states. I've also grown to despise moving. As far as friends go, I didn't have too much trouble, but it sucked every time having to leave all my friends behind. Very few of my friends from previous cities have I kept in touch with, but I still remember most of them, and miss them occasionally. I guess the biggest impact it's had on me is giving me a desire to not move my family any more than I have to when I have a family.
