A few years ago, I was convinced by one of my "buddy to riches" that the way to do it is through multiple streams of income. Initially, it started as making something every month that earns $20/month of revenue and let that accumulate, but as time goes on, I eliminated a few of them and ended up with the 4 I have now. My situation is in an awkward balance. Call it first world problems if you like, but since we are all here to learn to get richer, I might as well spill it: I cannot starve to death, but the wealth accumulation is also too slow. $100 when I only have $1000 net worth was great, but $100 at $10000 net worth is nothing.
I am of the opinion that this idea doesn't scale and I will be better off concentrating on one. Currently, if I want to grow any one of the 4 streams, I need to spend full days working on the idea, if I were to spread to all 4, that'd mean about 1 day per idea and before I know it, the week is gone. People say passive income is great, but often neglects to mention the upkeep part of any money making scheme.
So my question is, is this the way to riches and I am just not working hard enough? Or are people better off focusing on one idea once a comfortable base is established?
