Doing colouring with my two boys when they were little got me excited about how you could create a realistic picture from a few lines and some shading or colouring. We drew a few tardis and dalek pictures together, but right now they're not so interested. I carried on. I got a sketchbook and make myself produce 2 drawings a month. some I'm really pleased with and others don't quite work. I really enjoy closely studying and understanding the visual impact of what I'm trying to represent and I love the moment when you can show your picture to someone and they can see what it is you're trying to capture.
