These things may work really well at first and get great results but as more and more people adapt the same "perfect" system it becomes.... well... ordinary. One size of "perfect" does not fit all.
So what do we do with all the "perfect" programs we've purchased and are using?
We track the results we are getting.
We make 1 or 2 small changes and run the program again. Then we track the results we are getting.
We rinse and repeat until we are getting "perfect" results.
This idea can lead us away from the "perfect" program we purchased. I have found that if I stay close to what is taught but slightly tweak to add my own voice which resonates with my tribe, I get better results.
To me, "perfect" programs that have a proven success rate are a really good place to start. But when everyone else starts using it, "perfect" becomes common. Then it's up to us to add a bit of spice that transforms the results from naughty to nice... The people we dream of serving see us as leaders who dream big and deliver big because we have the moxy to add our own individual sparkle while still delivering great content.
"Perfect" programs allow us to build a solid foundation. But it's our creativity, content, and style that makes it uniquely "perfect" for our audience. And the results can then be... well, perfect.
