You could try:
1. Turn [silly] mode on? Click Wait or Sleep repeatedly and stop Withdrawing money?
2. Commission a dream scene where you swim in piles of coins when you sleep?
3. Realize that greed is a sin and ultimately the fleeting joy you get from luxuriating in a pile of metal that's sitting in a vault does no good for anyone. Formulate an economic and financial plan, where you spend, lend, or share the money on projects and goods that will stimulate the economy and your financial portfolio and ultimately yield dividends and security that goes beyond just more money, but towards a healthy lifestyle and outlook.
4. Take in your three nephews, Hubert, Dubert, and Louis (or find a hot duck/bird girl and have three younglings of your own) that join your family and share in your adventurers and lead you to realize that without family, you may have been wealthy... but you were never truly rich without them.
