There is a great scene in the first "Back to the Future" movie in which Michael J. Fox, as Marty McFly, takes over for an injured band member and introduces the tune "Johnny B Goode" to the audience, just a little before it is supposed to show up on the music scene. He tells the rest of the band "This is a blues riff in B, watch me for the changes and try to keep up."
Sometimes that is how life feels; we're watching for the changes and trying to keep up. In the movie, the band keeps up beautifully and the music is well received, until Marty gets a little too futuristic for them, and they drop out and leave Marty to go it alone. That also feels like life; sometimes the changes get ahead of us and we drop out, wondering what's happening.
