You need a password to enter: Whats the real message of Expedition 33 in one sentence?

I just woke up from a really weird dream. There was a secret Expedition 33 party but in order to enter you needed a password.

The question was: “what is the core message of expedition 33?”

In the dream me and my friends made quite a few guesses:

“See things as they are, not what you want them to be”
“For those who come after”
“Its all about art”
“You have to let go and move on”
“There is no black and white, just in between”
“Nothing good can stay forever”
“You have to enjoy what you have while you have it”
“Friends are your real family”
“Hold on to what you love”
“Parry it!”
“Dont be whooo be wheee instead”

None of them worked. So my question to you:
What would you say the password is?
