Artists are as diverse and varied as they come, not only in experience (or lack thereof), but style and attitude, yet many things are shared, from meditative time alone to a mutual love for aesthetics and the cathartic feelings that stem from purging our imaginations and desires onto a sheet of paper or canvas.
The beauty of art is that it can be picked up at any age. If art looks magical to a beginner then that's probably because they never spent any real time painting or drawing since leaving school.

The process of seeing can be mastered by all, and seeing is the key to drawing and sketching, and drawing/sketching the key to using any medium. Drawing largely amounts to measuring, coordinating the hand to interpret a representation seen by the eyes. The more accurate those measurements, the more like the subject that drawing will resemble (true, it can be easier said than done!). The basic skills learnt correctly can lead you towards your goals be it striving for photorealism, expressionism, impressionism or anything inbetween.
