Kenny's Learning Diamond:
Note, that the top of the diamond says "Play Effortlessly". That's a constant along with any two of the other points. More info on playing effortlessly here:

I highly recommend this book!!!!
Now, about the rest of that diamond:
Play Fast > Play the Entire Example (have to give up "Play Perfectly")
Play Perfectly > Play the Entire Example (give up "Play Fast"... in other words, play it as slowly as needed to not make mistakes).
Play Fast > Play Perfectly (perhaps give up playing it all the way through, work on a small portion until fluent/perfect).
