After a week off from work, sorting out life and trying (somewhat unsuccessfully) to relax a bit, I did come to an important realization. Our ability to be awesome doesn't have to come strictly from within. A little inspiration can in fact go a long way.
I suppose our culture tends to champion the individual who can, through sheer will and perseverance, conquer all. It's a pretty unrealistic view of the world, because most people just don't have it in them to be like that. It's not a character flaw, it's just the way it is, and I liked it to my perspective that the scope of your influence on the world isn't important as long as you have any positive effect on it. For "normal" people, external factors, inspiration, can make us better.
Our muses come from many places, and mine come largely from music and movies. Every once in awhile, there are specific people who also inspire me, some I know personally, some I don't. Events that have a positive impact on the world can be inspiring. Sometimes, even a piece of technology can inspire.
I've spent a lot of time recently being very heads-down, focused on the search for my inner inspiration. While that does certainly come in waves, it's the external things that really wake me up and move me forward. I need to make a more consistent effort to look for that inspiration.
