This is an analogy of what they're doing:
They're driving in a car following a GPS unit's instructions and they hit a HUGE mixmaster like this:
(which in IM means they were already on ONE course and decided to go buy a bunch more).
Now they could continue following the GPS's instructions and reach their destination (aka make money using the original course), but Noooooooooo...they won't do that.
They want to see the BIG PICTURE to make sure they're on the right path. They want to pull over to the side of the road, and try to zoom out and see each turn and street they might go on IF they follow each of the roads individually. (aka: are they making a mistake ...being an affiliate marketer, setting up AdSense, writing an eBook, etc.).
So they wind up sitting on the side of the road for too long, never reaching their destination - maybe even running out of gas (like when they post here or email me that they're overwhelmed and maybe quitting).
SCREW the big picture, folks! It's a big hot mess like the intimidating scene in the picture above!
You're never going to make money that way. Heck put the thing into practice FULLY before backtracking and choosing another route. And that doesn't mean halfassing it, either. Don't put a little bit of the product into practice. At least try the steps before coming to the conclusion it doesn't work. Or find an alternate way to implement the step, but DO it first.
There have been some products I wound up not liking, but I completed them and they ARE making me money - 1 yr later! But maybe it wasn't the scenic route I wanted. Oh well, try something else!
But stop pulling over to the side of the road to try to figure it all out. Such a waste of time!
