Cool! Serious patience is needed for beauty retouching. I get bored easily. It's why I don't shoot too many beautiful portraits.

there is probably efficiency criteria. If you get paid well enough for some beauty shot that will be printed out and placed somewhere on a billboard in a city you give it much more time. For general purpose internet sharing it is not efficient to give it 10 or more hours to work on an image.

You are correct.
