Hi mate.
You ask to start your PU career after reading 'The Game'. Excellent, i would say: the adventure start completely with.... YOU.
You want to learn the Mystery Method? Then read the mystery method, go out and do the mystery method. You only read half? Still, go out and do something you think might be working. dont do it once, do it always.
Things will start to change, you will get successes at some parts, fails at other parts. Learn from both, let your success and your fails be a source of your confidence. You failed, but hell, you wanted something and you went after it! Let that be the core of your existence.
Learning the Mystery Method ( or any other freaking method) get you there? Nope it wont. Even my advice will not get you there in the next month. Then what will it do? It will get you started, as you requested

and where you should start.
Besides, one more thing: before you log onto your computer to ask a question on this board of something you have read, go out and try your interpretation. Then come and ask what went wrong

.
We like people who go out and try stuff. We dont like textbook people, who want to look all guru 'because they read and fully understand 100 dating books'.
Ask questions about experiences, then you shall receive answers that will actually teach you something.
Lots of luck!
