Yep, I used to be afraid of putting the yeast in if there was salt added already, so I forgot the salt more times than I care to admit. Also (before I got my second, aluminum peel), building my 2nd pizza on the peel before I had taken the 1st one out of the oven. Forgetting to dust the peel is occasionally an issue. Until I started measuring by weight, I would frequently end up with a dough that was too wet, and then too dry, and then too wet again. Now, of course, it comes out exactly the way I want it to.
