Being an average Joe can allow you to blend into the crowd without people noticing you. This can be very helpful so people will not take advantage of your wealth. Living modestly and humbly is how some of us grew up.
Empathy and humility go a long way in life. Life should not be about bragging and boasting about new riches or wealth. We need to learn to be generous, have some humility, and practice being empathic towards others.
If you can keep your spending to the same people, you will never notice if you have a lot of money. Keep in mind that your actions shouldn't change because you have money. It would be best to practice humility and not flaunt out any extra money.
