Lift your foot up and try to balance in your seat and see how it feels. Try using a standing desk with it. Put a pen between your toes and try to draw a square and feel major muscles in your upper thighs struggling to make these fine control motions. Put on high heels and try to do anything that isn't gross movement. Sit in a train/plane/car and think of trying to use a laptop with a foot controller. Heck, put your mouse on the ground right now, turn pointer speed down as slow as possible to accommodate the gross movements of your legs, and try to use it.
