Just Keep Listening
One of my most favorite songs is Canon in G. One of the reasons I love it is because it builds and builds, getting stronger and more powerful and becoming more broad with each moment.
Life is a lot like that.
I came across this song. It's a wonderful song of listening, striving, and playing our part (no matter how small). It compares us and our lives to how a symphony is, with each instrument playing its part, and all of them coming together to make something better than what any one alone could do.
Here's another version whose music and video go together.
