<human>:  What types of investment strategies are best suited for long-term success?
<bot>: The best investment strategies for long-term success are those that are well diversified, have a mix of low-risk and high-risk investments, and focus on long-term goals rather than short-term gains. Common strategies include dollar-cost averaging, which involves investing a set amount of money over a longer period of time; index fund investing, which helps spread out risk by targeting a broad market index; and investing in actively managed funds, which are run by a professional who makes changes to the fund based on market trends. Additionally, putting money in tax-deferred retirement accounts like a 401k or an IRA can also be an effective strategy for long-term growth.
