+1 here on lack of sports and always picked last when I was younger. At least, that's the image I had of myself, and it was true for many years.
But I played basketball in junior high anyway even though as an 8th grader I was put on the 7th grade team and a couple of 7th graders were put on the 8th grade team. And I was in track for a couple years and I ran the long distance events because as a girl you could medal in those just for showing up. And I went through Basic Training and was actually put in the 2nd fastest group for training, and they worked us harder than the fastest group so at the end of it I ran 2 miles in 14 min.
I was overcompensating for my perceived lack of athletic ability.
