There are just as many people who say there are no limits (e.g. the sky is the limit), as those who say limits are good. I was profoundly affected by reading Rollo May's book on creativity when he spoke about how the creation of limits facilitated creativity. "
Creativity... requires limits, for the creative act rises out of the struggle of human beings with and against that which limits them. (Rollo May). " I saw this one today also which is from Robert Frost and it made me chuckle but how true it is.
"I play better tennis because the court is there. " (Robert Frost)
Anyway.....I made a pile of Indian Yellow, prussian blue and my new best friend, quinacridone red and of course white....titantium, white.....and painted five paintings; two landscapes and three still lifes.......I like the limits and I think there is unity.
