Katherine Russell said this quote

Sajib had said, What about happiness – can you measure that?Rodney had thought yes, you could measure it by ease of living –how much does a person suffer compared to the next? Now, to make more people happy, how do we eliminate suffering? But happiness, in its strength or fragility, was more complex than comfort. It had so many sources, so many nemeses, and so many pitfalls. He couldn’t, in his right mind, try to instruct the happiness of others.
