Chariots of Fire - I chose this motivational song because it's from a classic motivational movie. This is one of the songs I use during my visualizations where I imagine my goals as already being achieved. For me, since I've built such a strong emotional anchor to this song, it's extremely powerful in terms of activating my motivational energy.
I would guess that for many people, images of running in slow motion would come to mind made popular by many movies. To me, it conjures up images of winning, the internal strength of athletes, and the enduring spirit of champions.
