Is it just discipline? like they are already used to the habit of seeking methods to increase their income, the kind of discipline that got them wealthy and so they do not know how to relax after one successful business has been set up.
Could it be the expenses and lifestyle? like in trying to keep up with the bills they have that are big like maintenance cost for their PJ's and Yatch etc, they need to get more money to maintain the lifestyle.
What other reason could there be?
Inflation haha just kidding bro, they need money like we need but their expenses are higher than us obviously, if we are not poor but nowadays poor people are also spending money like they are rich haha. Rich people have to pay taxes, manage their finances and other maintenance cost because if they are too rich like they have their own private planes, then those are not cheap.
They are worth millions of dollars and whether they are using them or not they have to pay the maintenance and other repair fee and even have to pay the pilot if they have hired one.
Some rich people love to love a simple life so they are just focusing on new endeavors because of their discipline and they love to explore and test new things but those who have bought too many liabilities in this era, have to make money to pay the bills.
