Somestime you can find inspiration in music. Can you accept change in your way of thinking?

One of comments :

Have any of you ever taken calculus? The song is called delta, which in mathematical terms means change. In the Greek language, delta is a triangle. In this song, change is coming, (giant triangle) and they all try to fight it and can't beat it because you cannot stop or defeat change. In the end, the first guy who walked up to it accepted change, so the king followed. As they accepted change, it opened..And they all cried at the beauty of it.
