Last time I went in the darkroom to print, I turned on the water, got the negative boxes out and started riffling through. I had recently finished a few prints for two friends' of their weddings and that project left me somewhat exhausted and ran me out of some supplies. So this time I was looking for something for me. The only constraints, it had to be a good 4x5 neg that fits Grade 2 (because I was looking for something to go right).
Lesson learned: Pick the negatives you want to print - then turn on the water.
