Normal? Hmmm. Let's try something different.
Now, try writing down an idea on something that isn't typically a writing surface (wall, desk, baseball, box). Sit back, take in that idea on the wall, desk, baseball or box. Now, how do you feel? A little different? Do you feel like a genius who didn't have time to find paper to scribble down a thought, but had to get it out before that thought escaped forever to you settled on the quickest surface possible? I did. I hope you did too.
Making yourself feel like a genius is a good way to start any day. It's funny how changing a small thing, can make such a huge impact.
