Perhaps it is because I am not a cynical, greedy and uncaring author willing to make a quick buck off the desperate, lazy, uncritical or grief stricken but I really don't understand how it has been possible to take this very old idea:
Focus on your goals
And turn it into something that everyone seems to think is a brand new idea, whilst part of the selling point of your fake brand new idea is that it is indeed an old idea that has been around for ages.
If nothing else, I have to admire the sheer brass bollocksness of getting away with it.
