Give your analytical and planning mind a break. If you over-analyze your journals and stress out, you have missed the idea completely. It doesn't matter what color to use, where to place a piece of ephemera on your page, whether to journal in white or silver ink! Think process not product. Think relax, not stress.
<Lyrics> Look through your favorite playlists and find a song to be the muse for the page. You can work from lyrics to page, or create a page and then find lyrics that fit the feel of the page. Look up exact lyrics by googling the song title and "lyrics." I adore these lyrics to "Unwritten" by Natasha Bedingfeld. Another project using inspiring lyrics and quotes ~ Accordian Book: Quotes.
<Doodle> Imagery and doodling can be the start, or the final touch, to a journal page as described in Abstract Art: Imagery and Doodling. You don't need to have words on your page.
<Word Challenges> Limit yourself to adjectives. Sunny pale blue. Or limit to nouns or verbs. Or to words starting with the same letter or sound. Or number of syllables.
<Mapping> Starting with an old map, add images from magazines or catalogs that remind you of the place on the map. It doesn't matter why it reminds you, it just does. See 6 Collages 6 Ways for ways to embellish and alter collages.
