This sort of comparison is a mental habit, and it leads directly to ill feeling of one sort or another: greed, envy, pride, jealousy, or hatred. It is an unskillful mental state, but we do it all the time. We compare our looks with others, our success, accomplishments, wealth, possessions, or IQ, and all of this leads to the same state — estrangement, barriers between people, and ill feeling.
