You know your done

[Trainer Monkey]

Good Luck Really I don't think it's childish. I guess now at least you have enough experience to train more effectively than you did when you started and you know how to not repeat past mistakes you've made.

For instance,taping your ankles,and having to shave,doesnt look nearly as bad as lying on the ground grabbing your ankle and writhing in pain.

My former Sensei whose in his 50's came off of numerous back surgeries,and bronchitis,to start teaching again,and finish the Long Island Marathon last week
I blame him

Sensei? What art have you trained in? (if you don't mind me asking)
