1. Get a book with plain paper that you like the look of. (I like a black 9 x 12 sketch book with 110 pages)
2. Get a pen that you enjoy writing and doodling with. (I like a narrow, black felt tip water based marker)
3. Make time each day to sit with yourself and write a bit, (The morning works best for me. I have a comfortable chair in the bedroom overlooking my pond and the bay in the distance.)
4. Just start in with the date and the weather and how you feel. Try not to get too focused on the day's to do list. If necessary, jot it down and get it out of the way so that you can move onto ideas and images. Just write a bit about stuff you might like to paint and doodle at bit and once you get into this habit ideas just seem to pop into the book.
