I think it is pretty rare that someone hasn't had a few years of college. Remember the classes, homework, studying? Remember when you finally found a class that piqued your interest, that you want to study, research and are just flat out fascinated by?

The difference between graduating from college and graduating from writing is that we don't have the fancy little chart to outline just what needs to be accomplished to get there, and not everyone gets there the same way.

The key with the whole process is patience. It is essential to remember that just as we wouldn't expect to go to college for six months and graduate, we can't expect to write for six months and have agents and publishers beating down our doors. It is a process, learning patience and the craft along the way.
