Webster lacked career plans after graduating from Yale in 1778, later writing that a liberal arts education "disqualifies a man for business". He taught school briefly in Glastonbury, but the working conditions were harsh and the pay low. He quit to study law. While studying law under Future U.S. Supreme Court Chief Justice Oliver Ellsworth, Webster also taught full-time in Hartford—which was grueling, and ultimately impossible to continue. He quit his legal studies for a year and lapsed into a depression; he then found another practicing attorney to tutor him, and completed his studies and passed the bar examination in 1781. As the Revolutionary War was still going on, he could not find work as a Lawyer. He received a master's degree from Yale by giving an oral dissertation to the Yale graduating class. Later that year, he opened a small private school in western Connecticut that was a success. Nevertheless, he soon closed it and left town, probably because of a failed romance. Turning to literary work as a way to overcome his losses and channel his ambitions, he began writing a series of well-received articles for a prominent New England newspaper justifying and praising the American Revolution and arguing that the separation from Britain was permanent. He then founded a private school catering to wealthy parents in Goshen, New York and, by 1785, he had written his speller, a grammar book and a reader for elementary schools. Proceeds from continuing sales of the popular blue-backed speller enabled Webster to spend many years working on his famous dictionary.
