Anthony's put his finger on it with the phrase if you like things like that. What yo will get most out of depends on where you want to go.
Kiyosaki is excellent if you want to establish a self perpetuating, very high standard of living. For organisational aspirations, i.e. to build a big business employing lots of people so have an emphasis on personal power rather than wealth, take a look at Michael E Gerber's The E Myth Revisited. For self motivation, you could open some of the tried and tested stuff like Think and Grow Rich, but a health warning: much of the motivational stuff is done by very obviously religious people - Christian religious, specifically.
You could fill libraries with the stuff. If I ever have to choose the best sales motivational book I ever read, if you can stand the southern USA redneck drawl which, believe it or not, even comes out in his writing, it's got to be Tom Hopkins' The Official Guide to Success.
