Painting challenges - 30 in 30?

I have joined in two of Leslie’s challenges and the progress I made was amazing. I would encourage any artist to do the same. This January when I took up the challenge again I set my own challenge - to paint each day plein air. This I managed to do in spite of the frosts and rain. The idea being - if I can do this then I have no excuses. What happened? I slid back into the studio and had days of not painting so - bring on the next challenge, I’m up for it. Plus, committing yourself publicly gives you more incentive.
