We should also decide what interests we should cultivate for our own
personal development and happiness, and for the service we are to render
in a sphere outside our immediate vocation. We should consider
avocations as well as vocations. Whatever interests are selected should
be carried to efficiency. Better a reasonable number of carefully
selected interests well developed and resulting in efficiency than a
multitude of interests which lead us into so many fields that we can at
best get but a smattering of each, and that by neglecting the things
which should mean the most to us. Our interests should lead us to live
what Wagner calls a 'simple life,' but not a narrow one.
