Thats a great question. I definitely do. What I do is that anytime I see an image that inspires me in anyway I add it to my Evernote. Before any shoot I will research the model by looking through all or most of their photos. Find out what angels I like on them, how I think they look their best. How I think they will be most comfortable. Then I look through my Evernote and with the ideas I have from looking through the models work, I start to collect photos that I think could generate a cool look. So really the way that I rejuvenate my creativity is by looking through the work, photos, paintings and art in general that inspires me. By having that collection of inspiration at my finger tips at any time, its like having a customer made writers block crusher.
As for actual writing, not ideas for photography, I actually have stolen my idea from photography stuff to do the same. I have collections or writing, quotes, passages, chapters, in my Evernote that I will read through when I need inspiration or idea.
Essentially what Im saying is that Evernote has become my brain repository, and I rejuvenate it by re-reading/revisiting the art that has inspired me.
