Writing can be a truly bloody occupation. To be a successful writer, you have to want to write. You have to be willing to do the work. You have to be constantly educating yourself and improving your writing. Frankly, you have to like the work of writing more than the idea of writing.
Many people trap themselves by clinging to the fantasy of being a writer.
What they really want is to make easy money. They want to live the writers-life commercial. We are seduced and manipulated by the advertisements in our head - the ones that lure us in and spit us out. On your journey as a writer, you must pay close attention to what is motivating you to write. You don't write because you want to work at home.
