There are too many books like those, so i ended up borrowing
some at libraries so that the money wont be wasted on books that i
dont find so good
There are many books ,for examples, on persuasion and influence,
like How To Win Friends and Influence People by Dale Carnegie. But
one useful book that stands out is Robert Cialdini's Influence: The
Psychology of Persuasion. The writer is an academic professor, but
he didnt like dump in a pile of dissertations or theses. He
combined his personal research with some established theories and
worked in many sales line to build up material for this books. Very
informational, mind blowing and very to the point.
I think another outstanding book i heard of is Freakonomics, but i
have not yet touch on those.
