Things Don't Change, We Change

As above, so below. I believe that's what this concept might be reflecting.

The world outside doesn't change, not really. It is a reflection of how we feel. That is something I already knew.

So how can I use this?

Things do change because we change. That the outside world looks brighter is the change. It is that I experience it that it becomes real to me. So, to make it real to you...

I just need to point it out. That's it. I just need to show you and you will believe me.

That is step one; Look: Beauty (beautify)
