I think we've all been there at some point. First thing, do you have a writer's book? I do. It's a small notebook and I write all my ideas in there. It's in my purse and I take it everywhere I go because sometimes I get inspired by something I see or hear someone say.
Sometimes we do things that for us are so natural, while to others, it's amazing! I bet if you write down everything you do for a couple of days, beginning from waking up in the morning, brushing your teeth, etc you will look at it at the end of the day and see a ton of ideas you missed because you take it for granted, since it's part of your routine.
Maybe you cook something you like, or make a specific sandwich a certain way, maybe you find ways to cut costs at home, or you make something or find an easy way to do a chore. Write it all down. And look at your friends for ideas. How you relate to them, your relationships, your pets, your children, where you live, your neighborhood.
The world in your eyes will not be the world in my eyes or your readers eyes. That's why we have writers. We all have our own unique vision and that's a beautiful thing.
I have an idea for your hub. Title: Writers Block and Why I Hate It.
