Speech to students at the California Institute of Technology, in "Einstein Sees Lack in Applying Science" http://select.nytimes.com/gst/abstract.html?res=F50A1FFF3F5E1B7A93C5A81789D85F458385F9&scp=4&sq=&st=p, The New York Times (16 February 1931)
1930s
Context: Why does this magnificent applied science which saves work and makes life easier bring us so little happiness? The simple answer runs: Because we have not yet learned to make sensible use of it. In war it serves that we may poison and mutilate each other. In peace it has made our lives hurried and uncertain. Instead of freeing us in great measure from spiritually exhausting labor, it has made men into slaves of machinery, who for the most part complete their monotonous long day's work with disgust and must continually tremble for their poor rations. … It is not enough that you should understand about applied science in order that your work may increase man's blessings. Concern for the man himself and his fate must always form the chief interest of all technical endeavours; concern for the great unsolved problems of the organization of labor and the distribution of goods in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.

Variant: The purpose of life is not to be happy at all. It is to be useful, to be honorable. It is to be compassionate. It is to matter, to have it make some difference that you lived.

Attributed to Emerson in Life’s Instructions for Wisdom, Success, and Happiness (2000) by H. Jackson Brown Jr., as well as numerous on-line sources since, the article "The Purpose of Life Is Not To Be Happy But To Matter" at the Quote Investigator https://quoteinvestigator.com/2014/11/29/purpose/ indicates that this quote is probably derived from various statements first made by Leo Rosten, including the following words delivered at the National Book Awards held in New York in 1962: "The purpose of life is not to be happy — but to matter, to be productive, to be useful, to have it make some difference that you lived at all."
