I dont get this and im not even that old. Im under 40 and practice didnt have to be fun, it wasnt expected to be fun, id spend a good portion of the season dreading practice because it was the hardest thing i ever did in my life, and yet we knew it was a sacrifice- the price we paid to go out and compete. I never dreaded competition and I was always excited and enjoying my time at a competition. It was a known thing that hellish practices were the fire you walked through to be ready for your matches. Even at the two colleges I went to, one of them was just like a described above. The other was more laid back but we never talked about fun. It WAS more fun but it was never mentioned at all let alone as a priority.
Why is having fun at practice so important now? Is it an instant gratification vs delayed gratification thing? Is it all kind of a lie? Im sure you could have caught me smiling a few times even in practices where i was praying the grim reaper would strike me down. I dunno.
