13 year old beginner
I learned when I was 12. I soloed very fast and could do anything. Now I am 37 and find in the last year that I actually think about a maneuver before I do it. Never used to do that. I really sux. My friend says he is starting to do the same thing. I liked it so much better when I didn't think about it. Most things are still just done, but new things I tend to think through.
Your son will be very good. Hope he keeps with it. Kept me out of trouble all through high school and college.
