How old is "The Secret"

Well how old are you? In this book the author stated that

"The law began at the begining of time. It has always been and will always be"

So did you know about it? Or was it something that you never thought about. I never put it together that it was that powerful. Sure we all were kids at one time and thought if we wished hard enough for that new toy that it would be ours. But what happened to that as we got older?

Bob Proctor stated

"Wise people have always know this. You can go right back to the ancient Babylonians. They've always known this. Its a small select group of people"

So did we know or did we even think about knowing? Why did we not practice it before now?
Well I dont know why now or why not earlier but lets try it now. Why not right if nothing else it will make your day better thinking positive always does Right?
