Our virtues are voluntary (and in fact we are in a sense ourselves partly the cause of our moral dispositions, and it is our having a certain character that makes us set up an end of a certain kind), it follows that our vices are voluntary also; they are voluntary in the same manner as our virtues.
My feeling about work is it's much more about the experience of doing it than the end product. Sometimes things that are really great and make lots of money are miserable to make, and vice versa.
