I did my 21 days, painting a quick (20 minute) painting every day!
It was a very good exercise. Karen Margulis gave the workshop group this challenge in order to make us start a new habit of painting every day. For me it is usually hard to do.. there are so many excuses, the house is a mess, the phone rings, I must cook and it goes on… it is never my turn to just do my thing. I think this really lowered the threshold for me, and made it easier to just START a new painting. At least I can say I have never before painted this often! Before I often thought I had no time, and ended up painting nothing!
The point wasn’t to create finished pieces for framing, but to just paint for a while every day. It gets you going, You should try!
