Whether you think you can draw or not, it's worth watching this short clip of award-wining designer Milton Glaser talking about the importance of drawing as a life skill. (While drawing, of course.)
Select quotes from Milton:
Drawing is how I think.
Accuracy is the least important part of drawing.
Art schools have abandoned drawing in order to make time for all the software they have to teach. We get what we need for our professional life but don't have an instrument for understanding the reality of life.
