Take a nap. It works for me about 90% of the time. Usually I wake up with at least one great idea for a blog post.
When I got home from work tonight, I had no idea what to write about. I was tired so I took a nap and now I have two ideas–this post and the one I’m about to write, which will be a lot longer.
Your brain is like a computer. While you sleep, your brain performs maintenance tasks–the biological equivalents of defragmenting and disc clean-up. More space is allotted in your conscious mind for ideas to bubble up from your unconscious mind that were trapped there before and you couldn’t access.
It always surprises me how often I’ll wake up from a nap with some idea I’m just itching to write about, but before I went to sleep it just wasn’t there.
So next time you can’t think of any ideas to write about, try taking a nap. I bet it will work for you too.
