You do not invest
The money you save every month is unlikely to make you rich unless you invest it wisely. If you park all your money in a savings account your net worth will in fact decrease due to inflation.
The same applies to certificates of deposits and other low-risk investments that pay next to nothing in interest. The returns you get from such investments are not sufficient to improve your financial situation in any meaningful way.
Unless you invest in equities and real estate you are unlikely to acquire a substantial amount of wealth in your lifetime.
