This sort of thought process is why I’m pursuing my writing career. I have no idea whether it’ll make me a millionaire or a grown man living at his parent's house for all time. Of course, I’d appreciate having money that I could move out one day and I’m committed to that, but the fact still remains that this is the path I wish to walk, even if it makes no sense at all.
I think it’s important to find that path and to pursue it to the end. You never know where it’ll take you.
