"Fellows, you're going to receive some criticism. Some of it will be deserved and some of it will be undeserved. Either way, deserved or undeserved, you're not going to like it.
"You're also going to receive some praise on occasion. Some of it will be deserved and some it will be undeserved. Either way, deserved on undeserved, you're going to like it. However, your strength as an individual depends on how you respond to both criticism and praise. If you let either one have any special effect on you, it's going to hurt us."
Ironically enough, I read this on Saturday night, while I was at Black belt camp.
