Most artist know this but it is a good reminder to myself. The more projects I have in front of me, the better I work. Especially when it come to working with art the old fashioned way. In working with watercolors this is very important. You need to distance yourself from it and in doing so, you get perspective which makes your art better. As well, stop while you are ahead and feeling good about where you left off. It will be easier to go back to.
