paint the impossible 'paint'

I watched 'Global Trekker' and noted that Renoir suffered from arthritis. He still painted. And Matisse in his old age used new method to do his artworks in Chapelle du Rosaire de Vence - a seemingly very serene place. I found on line a book about this little chapel: http://www.amazon.co.uk/Henri-Matisse-A-Second-Life/dp/0241969085 There is no easy life. If we hold on to our dreams, even during sufferings, we would be 'revitalized' in new form. And creativity is a gift from God.
