Actually I thought it was pretty clear. There is a lot of stuff out there about why traders fail. If you don't do any of that stuff you'll be way ahead of anyone who has to learn the hard way. I'm not going to do your work for you!!
The technique one trader uses but fails at, might be the very same technique another trader uses and succeeds at. There is no shortcut as you imply.
I'm not implying a short cut; I'm giving you a different approach. There's still work involved. If you feel it doesn't apply to you then feel free to ignore it.
