The-Conquest-of-Happiness-by-Bertrand-Russell

in those rare moments when he examines his soul,
the most varied and interesting assortment of
ingredients being dissected and recombined into
beautiful or instructive patterns.
The forms of zest are innumerable. Sherlock
Holmes, it may be remembered, picked up a hat
which he happened to find lying in the street. After
looking at it for a moment he remarked that its
owner had come down in the world as the result of
drink, and that his wife was no longer so fond of
him as she used to be. Life could never be boring
to a man to whom casual objects offered such a
wealth of interest. Think of the different things that
may be noticed in the course of a country walk.
One man may be interested in the birds, another in
the vegetation, another in the, geology, yet another
in the agriculture, and so on. Any one of these
things is interesting if it interests you, and, other
things being equal, the man who is interested in any
one of them is a man better adapted to the world
than the man who is not interested.
