I found all of Gerbers stuff to be crap and airy-fairy stuff, but he is surrounded by a emperors new clothes syndrome.
every one knows it a load of crap but no one will say because they think they will be the only one who thinks it and will look foolish. but its all crap!!
these are the books i recommend;
Time Tactics of very successful people. B.Eugene Griessman
this book is brilliant to have next to the toilet for when you are having a good poo and need a good read to make the perfect experience. you can open it at any page, read a couple of pages and learn something useful.
Change your thinking-Change your life. Brian Tracey
another book that has wisdom on every page. Chapter 3 'dream big dreams' changed my whole business philosophy
How to say it. Rosalie Maggio
just as it says on the tin! tells you how to say or write the correct thing on every occasion .
these book are easy to read and not aimed at university educated people, they are good books for the common man
