I don't have much to boast about as I've never been the best student in my class.
The two things I'm proud of is my horse ridding level (after nealry 20 years of lessons), I've ridden a crazy horse that was spooking randomly, mostly in the corners but it could happen anywhere
I was one of the few with enough balance to stay up there! Then after coming to China I taught a mongolian race horse to jump. He was very good but always coming 4th so they stopped his racing carreer. I had never rode a racing horse before and was surprised to see his big shoulder and tiny butt
It took me some time to teach him to put his balance on his hips and then we started jumping. He loved it :p
The second thing that I'm proud of is my mandarin level. I'm not as good as some famous "foreigners" here but I can manage most situations quite well.
