One of my teachers, a highly skilled martial artist, would often talk about the horrible teachers he had coming up through the ranks. He would talk about how he got through it and how he knew much of what they told him was wrong. I used to just write this conversation off as ego talk. Now I am convinced that the crap teachers were instrumental in making him a great martial artist.
And I'm sure that sounds like a big load of crap to you, dear reader.
