I have a Moleskine notebook that I use to write in. I just use it to jot down ideas that I have that are not fully developed but that I think are intelligent. I also write down quotes that at the time I think are relevant to my life.
I was leafing through it today, this one made me smile today:
"If you want to catch beasts you don't see everyday,
You have to go places quite out of the way.
You have to go paces no other can get to
You have to get cold and you have to get wet too."
Dr. Seuss, obviously.
Ok, one more:
"There will come a time when you believe everything is finished...
That will be the beginning."
