I learned to skate (meaning stand up and move without ending up on my butt) after a few hours on a frozen saltwater cove. I got a cheap pair of figure skates but kept tripping on the lower prongs, so I filed them off and it went much smoother. After I decided I was going to continue, I bought a pair of hockey skates for slightly more money.
I did get to the point where I could go forward, pick up some speed, and spin around 180 degrees, but I couldn't keep up the momentum . . ."There he goes, he's moving fast, he spins and is going backward . . .ah, he's slowing down."
