I think the section on Fear struck home the most where she wrote, "This technique is being used by every other person. The best way to get something done from other person is to from a fear in him of losing something that is very important and this is exactly what most clients or employers do. From the fear of getting fired or staying out of work, people agree with working on the terms of manipulator."
Walk away power is so vitally important either as a freelancer, agency owner, or even an employee. This is where managing personal finances and business finances to the point that you do not need their money right now is very huge.
Also interesting about this point is that it goes both ways. Often times the client needs the developer more than the developer needs the particular client. Sometimes they realize this and other times they may not. That's just all part of the big game of life, I suppose.
"One way to trick freelancers with little or no time, is to write an attention-grabbing headline and follow it up with nothing. Job done..."
However... yeah, as noted in other comments here, I can't see how anyone would get through this and take it seriously enough to let it impact their professional lives given the poor writing, editing, and the copious amount of garbage framing what might be a few good pointers.
Obviously when I refused to send the work without payment the money arrived the same day (it was a subcontracted thing, so I guess they really needed it as well).
