People are creative beings. This means that they have a need to create things. In some people this need manifests itself in a different way. This is why you might see some people having a bigger need to create than it can be observed in other people.There was always a kid or two in my class who enjoyed drawing and painting more than anybody else. I would not be surprised if all those people I knew who enjoyed drawing specialized in affordable logo design today. If somebody likes doing something, he should keep doing it as long as he has fun with it and as long as it gives him money.
