Nita Engle was an American watercolorist. She worked as an art director and magazine illustrator and exhibited in and out of the United States. Engle received several awards, including an honorary doctorate from Northern Michigan University. A documentary was made about her entitled Wilderness Palette - Nita Engle in Michigan and she wrote the book How to Make a Watercolor Paint Itself: Experimental Techniques for Achieving Realistic Effects.
Because watercolor actually moves on the paper, it is the most active of all mediums, almost a performance art.
I equate inspiration with desire ? the desire that moves us to be artists in the first place. To attempt to make a painting without this motivation is a waste of time.
Gather and hoard your inspirations as you live, then recapture them as needed in the studio.
Anyone who tries to make a living as a painter knows you can't lounge about waiting for inspiration to hit; nothing motivates like keeping a roof over your head.
