How can a believer acquire contentment and get rid of daydreams that negatively affect focus in worship and life in general?

Contentment is a great station and a sign of success and salvation. It is true richness, as stated in the Hadith: "Richness is not having many possessions; rather, richness is the richness of the soul." Contentment is not about being satisfied with the inferior or lacking ambition. Rather, it is about disciplining greed and preventing avarice, and being pleased with what Allah has bestowed upon a person that they cannot change. Contentment can be acquired by being pleased with Allah's decree, by training oneself to acquire this characteristic, by knowing that it is a source of strength for a person, and by refraining from wishing for what Allah has favored some of us over others.
