When I say that they might not understand what you are going through, I am talking about them getting a bit negative about the reality of your current situation. Sometimes they may say or do things that discourage you and that can make doing what you want a whole lot harder.
I am not just writing this post from the comfort of my own home and my own desk, but I know what it is like first hand to have those you love most, doubt you and your potential, not to mention the logic of your dream. Just because they do not understand what it takes to achieve your dream, does not make you or your dream impossible.
I though about this post last night, because I always have this problem and if any of you out there have this problem too, then I want you to know you are not alone. You can do this. You just have to stay strong, as nothing worth having ever comes easy. Being a writer is always tough and I doubt it gets any easier the further your career progresses.
