In my opinion, spending more on payday doesn't necessarily mean they're not spending wisely. If someone takes a salary and saves from it, while also saving an emergency fund and other important funds, they can still spend some money on things they want or need.
For example, a person might save 50% of their income, while the remaining 50% is used for living expenses, such as housing, food, and transportation. Once they have met their necessary living expenses, they can spend the remaining money on things they want, such as clothing, entertainment, or travel.
Spending money on things they want can help them feel more satisfied and happier. So spend wisely. They should avoid spending too much on unnecessary things, and they should set limits for themselves.
While it is fine to spend some money on the things that we want, in my experience many people take this to the extreme and spend every single dollar they make on what they want, not understanding that whatever money being saved for their future on their pensions is not going to be anywhere near enough to maintain their current lifestyle, so they either learn to lower their expenses now or they may suffer the consequences once they do not have the strength and health to work anymore.
