<human>:  What are the most successful investments to start with if I am a first-time investor?
<bot>: The most successful investments for beginning investors are typically stocks, index funds, exchange-traded funds (ETFs), and mutual funds. Diversifying your investments across multiple asset classes, such as real estate or annuities, is also a good idea. It's important to understand your personal risk tolerance and goals before investing in any asset class. A financial professional can help you develop a tailored plan that fits your individual needs.
