The internet is full of various 'coaches' and teachers advocating this or that. If one observes closely, what the majority of them are saying one can see that they are advocating one or another form of concentration: prayer, gods, transcendental meditation, how to found a company in 4 hours (the one who is writing this is not running a business himself just writing the advice) and so on.

Now, why would anyone believe in what they say? Why believe? Let's say one can try 'focusing on the breadth' for a year. What would one find? Obviously that when one part of thought is trying to focus, there is always a underlying part which controls it (the controller, the thinker, the me). So there can never be 100% concentration, aside perhaps of total hypnosis (dream like state). The state those people want is hypnosis? Apparently it is so. Why? Because it's advertised as peace. Hypnosis is advertised as peace.. But wait.. you cannot stay hypnotized the whole time. In transcendental meditation they will say to you: 'Practice with this mantra for an hour or two hours a day.' So it's even more complicated, doesn't make sense at all. The aim is to have the 'peace' (= struggle to concentrate on the mantra or prayer or whatever) from the practice in the other part of life! This is all truly a conundrum. But what can one ask when it's all wrong from the first step.

The fragmentary perception of thought is full of contradictions. And nobody even notices it. A hypnotized person would not notice an elephant in the room.
