IB and self development books

Hi guys .

Is there any type of books you recommend to expand IB knowledge and get effective results when working online ?

Thanks

Dan Kennedy No BS Sales Success and Dan Kennedy The Ultimate Sales Letter. He is pretty good. Still a bit of a guru. But not really a tard who sugarcoats things. You don't need to buy his courses.

Just look at the gist of what he is saying and be willing to screw up.
