Answer:
He did not have to worry about having money or working, so he devoted most of his time just to write.
Step-by-step explanation:

On the other hand, the experiences he had in other cities and other countries opened his mind to hate different aspects of the daily life in France. As a result, he started writing some critiques about the rich families and about the different social classes that seemed to be brilliant to the people.
