What they really mean to say is:
Do not think at all.
People who think positive do not think.
All they want is for things not to change.
You can easily identify them by their flowery phrases.
All is well.
It will all turn out fine in the end.
Or, most pronounced:
Just let it be.
However, it would really be a good idea
If people stopped just believing in good ends.
Their view of reality would be less pink.
Reality, after all, could not care less about
What we humans would approve of.
In reality, matters are as they are.
And that is beyond good …. and bad.
