I do always have a pen in my pocket and it’s definitely something, you know I think anybody should always have a pen because as an author, as an illustrator, the best ideas don’t always come when you’re sitting at your desk.
Usually when you’re out walking or you’re traveling somewhere, something will, something will just pop into my head and if I don’t have anything to jot it down on in a couple hours it’s gone, whatever, the next day and I’ve forgotten about it. So yeah I try to keep a pen at least and then I, somewhere I can find a scrap of paper to write down whatever it was that I thought of in that minute.
