According to Nerissa, the reason behind Portia’s “little body” being “aweary of this great world” is the abundance of her good fortunes. As she believes, people with too much suffer as much as people with nothing. If she didn’t have that much wealth, so many people would not come to seek her hand for marriage and that too in a weird way of choosing a casket. Then her life would have been simpler and happier.
 
As Nerissa thinks, happiness lies in between of having too much and having nothing. She feels that the people who are neither too rich nor too poor are the happiest ones.

“It is no mean happiness, therefore, to be seated in the mean. Superfluity comes sooner by white hairs, but competency lives longer.”
