Naturally, I could go on and on...but I got a little bored and if this doesn't sufficiently display 'proof' then you're looking in the wrong place anyway. Real people, real clients, real results.
ALSO - these are real people who took real action. They've achieved high levels of success by deciding quickly, implementing fast and taking lots of action. So, if you want results like these it comes down to being decisive, taking action and doing the work...it's quite predictable. On the other hand, if you choose to do little work and question every step along the way the results are also very predictable.
