(A/N: Inspired by the quote 'Change your thoughts and you change the world' by Norman Vincent Peale.)
This world changes us.
You were different when you were younger. All of us were, really, before and after you – not one of us could have predicted this future. No one knew things would turn as they did.
The future cannot be predicted, but there will be change. We can strive for it to be positive, but there will always be negativity to combat, be it our own or that in the world. The world's neither positive nor negative, in reality, but those who occupy it influence it just as it influences them.
You were different when you were young.
