Who originally said "live like you're at the bottom, even when you're at the top"?

Question

please do not say the Jonas Brothers because they did not make up the quote

Answer 1

That's a tough one because it is mostly known for being a quote by the Jonas Brothers... an answer you don't accept...

That's why nobody answered till now...

I don't even know the Jonas Brothers...

I got another h int that you're right about a different origin...

“Our dad says, ‘Live like you’re at the bottom even if you’re at the top,” says Joe, 18.

The problem is to find where he's got it from...

I'd say the original has do have a different wording, otherwise I would have found it already...
