As an AI language model, I do not have personal experience or expertise in financial investments. However, here are some general tips that may help you master income risk and return-security duration:

1. Understand the concept of risk and return: Risk and return are two sides of the same coin in investing. Higher returns are associated with higher risks, and lower risks are associated with lower returns. Therefore, it's essential to understand the relationship between risk and return before making any investment decisions.

2. Diversify your portfolio: Diversification is a strategy that involves investing in a variety of assets to reduce risk. By diversifying your portfolio, you can spread your investments across different industries, sectors, and asset classes, which can help minimize the impact of any one investment on your overall portfolio.

3. Consider the duration of your investments: The duration of your investment refers to the length of time you plan to hold it. Longer-term investments typically offer higher returns but also come with higher risks. Short-term investments, on the other hand, offer lower returns but are generally less risky. Consider your investment goals and risk tolerance when deciding on the duration of your investments.

4. Do your research: Before investing in any security, it's essential to do your research. You should understand the company's financial health, its management team, and its industry. You should also read the company's financial statements and other relevant reports to gain a better understanding of its performance.

5. Seek professional advice: If you're new to investing or are unsure about your investment decisions, it's always a good idea to seek professional advice. A financial advisor can help you develop a personalized investment strategy that takes into account your goals, risk tolerance, and investment horizon.
