Several years ago I did a 3 month stint of Daily Painting. This was a Painting a Day experience and during this time I completed 70 small oil paintings plus some acrylic pieces and Magic Painting Shirts. There is an incredible amount of discipline involved with doing a Painting a Day, which is why I only lasted for 3 months.
Out of those 70 oil paintings, about half of them were worth keeping. The other half has since been recycled into something else. There is much to be learned from doing a Painting a Day, so if you haven't already tried it I would recommend it highly.
