I went by two phases - firt one, when I started and lasted about 15yrs - I was mostly a techician.
If I would, for some reason, get a bad neg I would get very mad - at myself, of course.
That's one of he reasons, for instance, I started using HC-110 diluting it from the concentate - I wouldn't run the risk of using less than optimal developer.
Now, after some 15yrs hyatus, I still like to do it well done - but if something (technical) goes wrong, it really doesn't matter, as long as I can get MY image.
Age helps a lot!
