While I've posted before about Hans Zimmer and his POTC score that motivates me as I get work done, there is another score that I shuffle in my iTunes for the same effect:
In particular is this track, which is where Peter, Caspian and Edmund (Mostly Peter) lead an attack on Miraz's castle in Telmar. I hope it motivates you as much as it does me, as you go about your Monday and fold laundry or clean the kitchen or whatever it is you have to do today.
As for me, I'll be finishing costumes (Due in 10 days!!!), sewing for a festival next month (have to be ready in 20 days!!!) and generally conquering the world. :)
