I have a ton of playing stuff that im proud of and competing also.
Over them all I rate working on my students. Especially one boy who was 13 when he joined my junior team that I taught to play.
He was getting in troublesome company and had problems in school and little ADHD too. Anyways he got into pool so much he focused it so much he ditched his bad company and focused to learn and play pool. He was good player already age of 15-16 but then he found lovely girl and wanted to get money and went to work on his father business to get some money.
He then started play and practice less and less and got married and get children early too.
Couple years later his parents came with flowers and wanted to say thank you for me. They said boy was getting in criminal company and that I inspired him to learn pool so much that it turned his life around.
I think if you can do that nothing else really will top of that.
