As a child, we all possess the ability to draw, the imagination, the will to do so. Picasso even said himself, that we were all artists when we were children. The problem is just remaining one when we grow up.
When my daughter was about seven years old, she asked me one day what I did at work. I told her I worked at the college - that my job was to teach people how to draw. She stared at me, incredulous, and said, "You mean they forget?" ~Howard Ikemoto
I've been drawing since I was a kid. I know when I was a kid, a lot of things just came easier and I would draw tons and tons endlessly with ideas and an imagination I can no longer fathom. There have been a few dry periods in my life where I just couldn't seem to create anything worth keeping. Sometimes I just didn't want to make anything or didn't have the drive to. Somewhere within all of us is still that wild four year old wielding his crayons and scribbling across stacks of paper the dinosaurs, spacemen, fairytale princesses, and knights that our minds come up with.
I think for beginning artists now, the best advice I could give is to recreate your childhood. Look into your soul and see the innocence you once had and utilize that to recreate the hurt and love and loss you feel today in your much older years. Going back to your roots is important, so break out the crayons and color pencils and draw and draw and draw until your fingers bleed. Draw everything you see, copy everything you see in your mind and in front of you. Don't ever stop. Even when you don't feel like drawing... draw! When you feel like drawing, draw! When you're hungry, draw your food! And so on...
Draw until it becomes second nature. Draw and paint and write until it becomes a sixth sense that many people obtain once they have lost their luster as a kid.
