It's a waste if one reads the above and not the paragraph following this one.
The Roman historian Sallust said of Cato "He preferred to be good, rather than to seem so". The lawyer who quits a high-powered law firm to work at a nonprofit organization certainly seems like a good person. But if we define "good" as helping people, then the lawyer who stays at his law firm but donates the profit to charity is taking Cato's path of maximizing how much good he does, rather than how good he looks.
