I'm mostly content with my height, but I stopped growing at 5' 11-1/2". The extra half inch would be nice, but I've literally been the same height since age 15. I was always one of the tallest kids growing up (and have some of my old class pictures to prove it), but one day I just stopped growing, and eventually everyone else caught up to and then started passing me.
I had hoped I would have one more growth spurt earlier this year (my Dad had one when he was 20- he went from 5' 11" to 6' 2"), but it doesn't look like it's going to happen.
