In many of the phases of photoreading (not the photoreading step itself), I am confronted with too many ideas too quickly and get overwhelmed. There's no time to think through each idea.


Why should you?
May be you don't need to think through each idea.
I read many times in the past you got good results by processing each idea.
That gives you self-confidence, makes you feel comfortable.
But if you're applying to learn photoreading, I think you want something more, or -at least- you think that you could give even more.
Well...get out your comfort area.
Your Life quality is as big as the quantity of uncertainty you can live with.
And...if you do things you always did, you will get the results you always got.
I don't think the reason you're studying photoreading is to get the same results of before. I hope you want more.

The challenge is exacerbated by the number of books which can be photoread in a short time. All of a sudden I am getting ideas from 10 books covering different subjects in the time it used to take to go through one-- and I am, at this point, simply unable to process the information effectively.


May be it's a limiting convintion.
Just think as you are able to.
