“The aim of the laborer should be, not to get his living, to get “a good job,” but to perform well a certain work; and, even in a pecuniary sense, it would be economy for a town to pay its laborers so well that they would not feel that they were working for low ends, as for a livelihood merely, but for scientific, or even moral ends. Do not hire a man who does your work for money, but him who does it for love of it.”

Henry David Thoreau, Life Without Principle 1854

It is far easier to excel when you find something you can love to do.  The one who does what he loves will do a far better job than the one who is just putting in the time for money.
