With NaNoWriMo (National Novel Writing Month) you have an average of something just over 1600 words a day, but if you plan ahead and write more in some days you can skip a day or two, like I skipped over a week when I was away in Florida.
With Art Month you have to create EVERY day so there is no working to get ahead or days off. So if your day gets away from you then your staying up late and drawing.
Though I have to say once I stop and force myself to create part if the world goes away and I get into this nice state if mind. That’s what this us all about.
the other difference is that this isn’t national or international yet, it’s just me :(
