As JBrunner mentioned, not making negatives, carefully picking your poison, is a big help in reducing frustration over quality on down the line. For me - obsessively sparse anyway - when I know I'm working on good stuff (to me) I'm well-wired during development and subsequent printing - of course that makes failures that much more disappointing. In that regard about a year ago I stopped being a cheapskate and started making 2 identical negs to protect myself and/or allow experimentation. Big Help!!
I've never regretted pitching crappy-looking negs right out of a quick rinse, and God, the prints I've thrown away! Some bad stuff I do keep if it links to my notes and can stand as an example of a screw-up, but I even dump that junk soon as that particular goof is no longer a danger.
rjas, In eight years of 8x10 I have 2, maybe 7, finished prints that I feel are really good, so maybe you're right on track?
The flip-side of my M.O. is I'd be a better technician if I'd make more negatives.
