Visual stimuli help a lot when you're trying to get into a creative mood! That's why creatives who can afford to have their own home offices make them so colorful and creative and just full of wisdom and creative flow.
See my Creativity Galore board, and create your own!
You can even take it a step further and create your own Creative Vision Board - online or even better, by hand and put it on your wall - where all of your passions and creative interests face you as you do creative work.
Spending this kind of energy and attention on your creativity and being in the presence of all the things you love will definitely have a great effect on your Muse.
