It's not fancy or new or flashy, but my notebooks are an incredibly important part of my work. I write down almost everything: to-do lists, ideas, errands, thoughts and feelings, drawings and quotes. It helps me to keep track of things, but also helps me to not lose sight of aspirations and hopes. I try to write in a different color pen each day. I've kept every work notebook I've ever used–it's the most complete record of my life!
