Did you ever play organized sports?
If you did you probably had a coach somewhere along the line that was very harsh, you learn a lot from those guys, they don’t want to hear what you think or why you tried to do something.
I had the good fortune to have one of my early shuffleboard coaches be like that, Dick Jenkins.
He’d tell me he didn’t want to hear what I thought or what I was trying to do. “This is what you do, now do it”!
I learned a lot and really got off to a good start!
Dave Stott was a lot the same way; he’d watch you and he’d tell you what you should have done and he’d didn’t always do it in a nice way but if you could stand the chewing out you learned a lot, I learned a lot from Dave.
I’ve been tempted to take the same approach with some of my students and some of them will probably tell you I did, but I’m not doing it now, probably because I’m not as passionate about seeing anyone succeed as much right now or maybe my reputation has preceded me and not many players argue with me.
