Apparently this is just my own personal idiosyncrasy but I'ma ef than should not automatically translate to, "I don't have to do a good job, so I won't." I seem to be the only one around here who thinks that completely phoning it in when I know for a fact I'm capable of doing better is not fun.
Indeed it may just be a personality thing. The way I see it, when you are given a challenge to do in a time limit, you must adjust your expectations of what can be accomplished. It's not about being sloppy, but doing the best you can with what you are given. There's a difference. If you always wait for perfection (or don't try because you are afraid of not meeting your expectations), you would get fired from most jobs, or worse, never try much at all. I see it as a risk. A safe one.
For instance my last entry was not great. I wasn't totally happy with it. I tried a new patter that didn't turn out how I had hoped. But it was fun, and I find value in participating.
My dad is a contractor and he used to build us forts as kids. They were not small houses with all the finishing. They don't need to be because they were just for fun. He would build one with us in a morning and then another week we would build another. Fun doesn't need to be perfect. Fun is in the journey.
And as for us working magicians, youtube as I mentioned has great features to keep videos unlisted. Or you can start a new account. But that's barely a reason to not play.
