With the mention of being a nature person, that brings up another question: do you find yourself being inspired by being out in nature, but more specifically when you're able to get away from it all for more than just a day or two? You mentioned you were moved by nature, but I wonder if you feel the creative juices really flow the longer you're away from 'civilization'. I find I always feel my most creative on camping trips and really itch to drawing something, which only gets more intense the longer I stay out in the great outdoors.
Actually the two places the most ideas come from for me, specifically for songs, is when my mind is occupied doing something else such as driving, showering, or mowing the lawn.
I like to take back roads where I can. Just looking around it's hard not to get inspired or look at the world with a sense of wonder...yet, have to be doing something else at the same time.
If I'm on a hike or just outside for an extended period of time; my mind shifts away from song writing and just enjoying nature.
I may be strange that way.
