Yes Man is also the name of a book by
Danny Wallace, in which he realises his life has become boring, that he isn't really living anymore when a man on the bus tells him to "
say yes more". This causes a change in Danny's attitudes, where he decided from then on to accept any invitation or suggestion for the rest of the year.
The book is exceedingly well written, and the principle of saying yes to things more has taken off to varying degrees in everyone I know who has read it. This can be deciding to go out when you could happily sit at home to telephoning your
phone neighbour and arranging to meet him.
In the book Danny has many amazing adventures, simply from saying yes to the most mundane of things, such as taking
hallucinogen in an
Amsterdam leather bar and getting a drawing of him with his invisble talking dog (reproduced in the book) after saying yes to a piece of
SPAM, winning £25,000 on a
scratch card, poking a
buddhist monk on
Richard and Judy (national TV) to losing £25,000 on
the tube.
