Find your muse and never let it go. This is where inspiration is born. It sleeps once in a while. This is OK. Don’t let lack of inspiration have you curse the lack of it. Sometimes your best work is done when you dream.
Go into each painting with the intention of success. Don’t think that what is in your imagination can’t be realized onto canvas. Practice until what you see is what you get. Once you are able to do this anything is possible.
Continue this if you want or don’t. Each work cannot be a masterpiece. Some works need to fail. Try and recognize which work(s) are worthy of your time and strive for resolve; from the work inside out. Keep your work away from dampness and holes. Without proper care, the work struggled over will be lost forever.
