In my discrete mathematics class at UT Austin, my professor taught us all choices have consequences. When doing math, we have to care. In a class on rings, we discussed 1+1. The biggest lesson turned out not to be what 1+1 is, but what we define 1+1 to be. For instance, if we restricted the range to 0 and 1, would the answer be 0? Or would the answer be 1?
Of course, the pursuit of happiness isn't all sunshine and rainbows and mugs of tea and smiling children. Sometimes we need to tackle our insecurities and weaknesses, and we can't just ignore our draining jobs and nagging relatives. But the practices here represent the other side of the coin, the one we often neglect: seeing, appreciating, and mobilizing the good.
