I do my best thinking in the shower...seriously! It's about the only time I get to myself all day and nobody is yelling, "Mommy." The only problem was I did so much of my thinking in the shower I would forget half of it by the time I got out. My solution...the Crayola Kids Bath Crayons! I keep them in our shower to write my ideas and thoughts down on the walls. I have made a grocery list, blog post ideas, things I need to do that day, all kinds of reminders. I first tried out the Crayola Bath Markers but the steam would make them run and after a minute, I couldn't tell what the word was I just wrote. Anyway, if you have too many thoughts and not enough memory (like I do) I hope this helps you out!
I got these at Wal-Mart for $3.97
It comes off very easily...I just use a wash cloth and water.
