I have a pad of canvas "paper" that I have been playing with.
When I had extra paint from the last painting, I had these there canvases taped up next to my easel and I used some of the richer colors to try to be abstract.
I also have visited the Rothko exhibit a few times and was inspired. After looking at the Rothko paintings I had a dumb-ass "I could do that" moment. If you look at his paintings in person, you wonder how they got as popular as they did because they are poorly painted. Don't get me wrong, I like his work, but I was amazed at how simplistic and primitive it looked and felt in person.
In some ways, it seems like this kind of gut level understanding is what he would have appreciated.
