Here is a great short video by Miton Glaser where he speaks about the importance of your ability to draw if you are pursuing any kind of artistic endeavor. Thanks to Jo Castillo for sharing this link on her blog.
This takes me back to my first year in art school in 1971 where we were required to attend two full days of drawing each week throughout that year. We had two different instructors and class one was for realistic, tight drawing where we set up still life, or had models, or sometimes had to draw from memory. Photographs and using a ruler were never allowed.
The second class was for expressive drawing where we were always chastised for tight mechanical drawings and always encouraged to loosen up and be more expressive.
In order to complete the hand in assignments for each class I had to draw every day throughout the 7 days of the week which was not a bad thing. We also were required to use many types of medium such as conte, chalk, and inks as well as charcoal, pencil, and sometimes even ball point pen or a brush.
The point here is that if you can draw well, you an do almost anything when it comes to art. Drawing truly is the foundation of all good artworks.
One of the books we were required to buy in first year was Drawing On The Right Side Of The Brain which in my opinion is the best book ever written on the subject. Betty Edwards goes through a good deal of very good exercises to do that will make you better at drawing, and is well worth getting.
