I used to be a perfectionist, now I just have high standards.
Sometimes it's pretty easy to get some 'good' prints, but there is almost always room for me to improve them. That being said, I have also learned to just 'relax into it', take it one step at a time, know that I will forget something sometimes,and other times everything will go the way I like it. It's just life. If it's fine prints I'm after during a printing session, I will be doing good if I get one fine print out of a days work. That includes refinements of filtration, time spent burn/dodge, tweaking time of development, taking notes on each change I have made, making a final work sheet for when I do reprint in the event someone wants to actually buy my print, etc. But generally, even then, it's therapeutic for me; working with computers, the last thing I want to do is go home and work on digital photos on a computer. Music helps, or like someone else said earlier - no music until a certain point of washing, whatever works best for you. The most stress is when I have a deadline, like finals time portfolio; then yeah, the "i'm pissed at my self for not starting earlier" begins....
