Things to avoid when you earn a lot or become rich are simple as be grateful and don't be greedy but both of these are hard to achieve and easy to say. If I rich like right now one thing I do is buy dividend stock or something similar that basically give me money in monthly basis without work after that I can surely enjoy the rest of money
If you want to improve in your wealth, I don't think it will be difficult for you to eliminate greedy in your life, because greedy has destroyed many investors and if you refuse to eliminate it, it will make you not to pay your debt, it will make you not to stay long in your wealth before you will go down to poverty level again. You mean investing your funds in different investments right, I think it will boost your financial status but if you invest wrongly, it will make you to return back to zero level in your investment, because there are some investment you must avoid if you don't want to lose your capital. Avoid storing your funds in the bank, because it will not going to add income to your saving and you need to avoid such decision, because it will not boost your financial status but if you invest funds in decentralized currency or estate investment, I think you will continue to enjoy your wealth in the nearest future.
