I've also let fear prevent me from many things. Learn to work past them and become what you've always dreamed. Write with abandon. For without your love of the story and the freedom to make it go the way YOU want it to go, you don't deliver what the readers really want. Sometimes, though it is often said we should write every day, taking time off can be more beneficial.
Writers are always on the job as it is.
We don t clock out at 5 each day, not to think of work until 9 the next day. Our minds work even when our hands do not. So make a conscience effort to break yourself away, even if just for one day your mind will thank you. Many of us grew up with the desire to become writers. But in the end, we write and write, hoping always to reach our dreams.
