I used to be able to tie mine up from an earlier age. It got to a point where I would teach my best friend how to tie her laces, and she in response would help me choose my left shoe from my right (it took me years to work out it was the way I took them off... take off left shoe, then cross leg and take of right shoe, dropping the right on the left side of the left shoe... then when going to put them back on I always thought they were ready to go)
