I try to live every day with this in mind.
Although I completed my Master's Degree requirements, I think it would be wise not to sit back on may laurels, but to continue to learn something new everyday. I like to challenge myself to work on areas where I know I am a bit poor, like drawing hands. My challenge to myself last year was to draw one hand per day for 100 days. At the end of 100 hands, surely I would have a better grasp of the gesture and form of hands, and it was true. I did. But why stop there. After that I challenged myself to draw one foot a day for 100 days. Feet are almost as difficult as hands and I have the very bad habit of drawing feet too small for the proportions of the body. After 100 feet I felt like I had a pretty firm grasp of the personality of feet. Then I thought I am a children's book illustrator and I have really spent very little time drawing children. Children's faces are really different than adults. They have larger eyes and less neck than adults. Their cheeks are fuller and the nose and chin shorter. So for 100 days I drew children's faces. It was quite the challenge because the faces took longer than the hands and feet each day but it was very rewarding.
Now what shall I do next? Another 100 children? 100 hands? 100 torsos? I haven't decided but I have decided I need to keep practicing to keep my skills sharp.
How about you? What do you do to keep sharp? I'd love to hear about it.
