What's the tub journal I keep talking about?

Okay, so if you’ve been following me on Twitter for more than a week, there’s a pretty good chance that at some point you’ve seen me mention a tub journal. I’m sure that many of you can relate to feeling like you have to multitask or things will never get done. Busy parents, I know you especially know that trips to the bathroom are sometimes all the alone time that you get. (Let’s be real. Some of our kids hunt us down in the bathroom too.)
Some people say they get their best ideas when in the shower. My most dominant shower thought is something along the lines of “Ugh, what am I going to do with my hair today?” Then is all spirals down to wondering what the kids are doing and what snacks need to be replenished, and what’s in the fridge to even cook, etc. Clearly, the shower isn’t my ideal clear thinking space.
Behold! The tub journal was born due to a lack of time, selective focus, and ideas that never quit. In reality, it’s a legal pad that I jot down all of my ideas. I don’t use it anywhere else unless I’m typing up my notes off of it. That’s the thing, since the tub journal can get wet at any moment, I always make sure to type up my notes before the next tub journal session. There’s no need to take a chance of good ideas getting washed away.
What about you? Do you have any odd note-taking habits? Surely I’m not the only one.
