Adam,
Welcome to one of the most honest and straight-forward forums on the web.
Your form of inquiry is not only welcome here but healthy as well.
I could tell you my life story but it is not only long but probably boring as well so I won't bother you with it. As I write this I am listening to one of the Bonus CD's Michael gives away upon signing up with LifeFlow (LF). I believe you can keep them if you choose to turn everything else in for a refund.
Someone here will correct me if I'm wrong; surely.
I practice yoga pretty steady; 4-5 days a week sometimes 6. I push it pretty hard so use the off days to let my muscles rest. I've been meditating for many years with a few short breaks in between. When I came to LF I seemed to be stuck in some sort of rut. My meditation had been flat-lined for some time and I was beginning to think that was as good as it gets; then I found LF. I too, was skeptical but the example that Michael has put most of my skepticism to rest and the forum took care of the rest. I bought in hook line and sinker and have never looked back.
Have I reached Enlightenment; probably not. Although, much of the time I am filled with a joy that cannot be described. All I know is I HAVE to share it with others. There is no choice; I find myself telling people I have never been happier in my life . . .or. . .damn it's FEELS GOOD to be alive. I just want to climb the highest mountain and scream for joy. I have more energy, my concentration level is up and I believe my thought process has changed dramatically.
But you know where the rubber meets the road?
At home!! My lovely wife and children have opened up to me in ways I never thought anyone would. My wife was actually a little fearful for a time because I was changing so fast although she was loving the results.
Meditation has deepened beyond my wildest dreams. This A.M. I meditated without any CD and my meditation was as deep or deeper than it has ever been. Because I was a long time meditator I still love to meditate without any aids sometimes. It's not a problem.
And I've not even reached the end of the series of CD"s yet. At this point I don't really care if I do. It's not as much of a goal as it used to be.
Micheal McKenzey and his LifeFlow system are the real deal Adam.
