A secret is a thing others think is impossible but you know is actually possible.
If you can sequence multiple secrets, no one else will even try to follow you.
Every time someone hits a "that's impossible" in a sequence they stop.
Sometimes they actually are possible, just requires doing something out of the ordinary, lateral thinking.
If your idea requires three of those miracle points that look impossible but actually aren't, then the likelihood someone else sees it is very low.
