What is the secret? Studying hard (or being born into wealth and power) can actually pay off! ;-)
I'm actually wondering what the secret is myself; however, I think the "secret" will probably not be that earth-shattering. If the "secret" is
really that powerful of information, I highly doubt the people who know the "secret" would actually let the "secret" get out - or let this show be
broadcast.
The secret to success is sincerity. Once you can fake it, you've got it made.
I can't confirm that's the correct answer as I haven't seen the show. If the show prove me right, I think I could even figure where the producers
got the idea.
