Holberg's travels were a main inspiration in his later writings – these experiences matured him both artistically and morally. Holberg let himself be inspired by old Latin comedies and newer French comedies he had seen in Paris, and street theaters in Rome.
Holberg's declared intentions with his authorship were to enlighten people to better society. This also fits in with the picture of Holberg as of the age of enlightenment. It is worth noting that Holberg enjoyed larger cities with deep culture – small cities and nature did not interest him.
Holberg had to live a modest life in his youth and early adulthood. He earned a living as a tutor and as a travel companion for noblemen and tried to work as a private sports coach at the university. He received further support from a grant to travel to other universities in other countries, namely Protestant universities, but it was a condition he did not respect since he searched out those places where the discussion were the loudest and the experiences were the largest.
To make the most possible profit, Holberg published his own works and sold them as papers under a subscription to interested people, either bound or in looseleaf sheets. Holberg also tried, with some success, a publisher in Norway. There, his book about natural and international law was printed in several editions but did not garner him financial gains.
Holberg lived modestly and was able to invest a large part of the profits from the sale of his books on the side and lend them out or invest them in more active ventures. Several times in his writings he criticized townspeople and nobles who used their resources in unproductive ways to be carried round in chairs, to live in lavish houses and waste money on luxury. He ate reasonably and did not use his money on being driven around. He said that his travelling on foot, and continued walking, was the reason he could keep his malaria, which had plagued him in the south, under control.
When he came to the conclusion he could put his money in better ventures than trading, he started investing in real estate. His first large property purchase, Brorupgaard close to Havrebjerg, happened in stages; first he lent money to the owner at that time, and later took over the farm himself.
Some years later, Holberg also purchased Tersløsegard by Dianalund, the only one of his properties which is preserved because the others in Bergen, Copenhagen and Havrebjerg have been either burned down or torn down.
Holberg's casket, a work of Johannes Wiedewelt, can be seen in Sorø Monastery Church.
It can be seen from Holberg's correspondence that he was very conservative with money where he thought it would not be of any use; for example, he was against raising the wage of the pedagogues of Havrebjerg.
Holberg commented several times that he was willing to use money if it were put to good use, for example, he would use money on medication and supplies for his farm hands if they suffered from injury or illness.
When academia had large economic difficulties, because funding was very limited, Holberg agreed to help fund the academy (at Sorø Academy) while he was alive.
There is a town named after Holberg on northern Vancouver Island, British Columbia, Canada. It was founded by Danish immigrants in 1907.
