You remember when you were maybe five years old and you went out in the morning and you looked at the day - and it was a very, very beautiful day.You looked at flowers and they were very beautiful flowers.
Twenty-five years later, you get up in the morning, you take a look at the flowers - they are wilted.
The day isn't a happy day. Well, what's changed?
You know they are the same flowers, it's the same world. Something must have changed.
Well, probably it was you.
- L. Ron Hubbard
