So why does adding pictures to our journals open us up so effectively?
Mostly because the visual side of our brains are our right brains - this is the side that is responsible for:
"big picture" oriented
symbols and images
present and future
philosophy & religion
can "get it" (i.e. meaning)
knows object function
SO when you choose some color and make a collage in your journal, you are in the right place to connect to your intuitive creative brain - and when you add words when in this place, you might just be surprized!
Add some color to your pages, add some lines, then write some words - see what happens.
