prosperous

Prosperous conveys a sense of sustained success and stability rather than a sudden windfall. It describes a state of being where wealth is not just present, but growing and flourishing. While "rich" or "wealthy" simply describe the possession of money, "prosperous" suggests a healthy, thriving condition. It often carries an aura of respectability and social standing, implying that the success was earned through growth or favorable circumstances. In formal greetings (like New Year's wishes), it functions as a hopeful projection of future abundance and good fortune. It is generally positive and avoids the connotations of greed or excess associated with words like "opulent".
