Minds change. They always have and they always will. And even though it may bring sorrow for some time, it is a good thing. 

Our ability to change our minds is the one thing that keeps us from living a monotone life, they keep us evolving. We make mistakes, we learn from them, we make good choices, then back to crashing and burning, and back to trying and eventually succeeding. That's just the way life goes. 

It wouldn't be fun if you would never change our minds, if we never dared to think about what it?

Our lives would be stuck in a sphere. When in reality life is a continuous line that either descends or ascends, life is a multitude of choices. Life is learning from the stupid things you said when you didn't quite things through. Life is being able to smile at your awkward moments. Life is trying, loving, laughing, crying, messing up, falling, then getting back up.

Minds change. And it's a beautiful thing they do.
