A quote from Robert Henri as presented in "The Undressed Artist" by Peter Steinhart:
"The sketch hunter has delightful days of drifting about among people, in and out of the city, going anywhere, everywhere, stopping as long as he likes--no need to reach any point, moving in any direction following the call of interests. He moves through life as he finds it, not passing negligently the things he loves, but stopping to know them and to note them down in the shorthand of his sketchbook....He is looking for what he loves, he tries to capture it. It's found anywhere, everywhere. Those who are not hunters do not see these things. The hunter is learning to see and to understand--to enjoy.
