Diversifying your income streams is important, but it's not just about having multiple investments. Start with two reliable sources of income and ensure they're generating money for you. Then, you can consider investing in another project.
However, don't hesitate to let go of an investment that's not working. If it's consistently taking money from you without adding value, it's time to reassess.
The key is to focus on the return on investment, not just the number of investments you have. Having multiple investments that aren't generating reasonable returns is pointless. You can start with one reliable source of income and gradually add more investments that provide value.
