What should I consider when I try to invest my money today for a larger immediate income stream that will secure my retirement?
TL:DR: You should read something like The Little Book of Common Sense Investing, and read some of the popular questions on this site. The main message that you will get from that research is that there is an inescapable connection between risk and reward, or to put it another way, volatility and reward. Things like government bonds and money market accounts have quite low risk, but also low reward. They offer a nearly guaranteed 1-3%. Stocks, high-risk bonds, or business ventures (like your soda and vending machine scheme) may return 20% a year some years, but you could also lose money, maybe all you've invested (e.g., what if a vandal breaks one of your machines or the government adds a $5 tax for each can of soda?). Research has shown that the best way for the normal person to use their money to make money is to buy index funds (these are funds that buy a bunch of different stocks), and to hold them for a long time (over 10-15 years). By buying a broad range of stocks, you avoid some of the risks of investing (e.g., if one company's stock tanks, you don't lose very much), while keeping most of the benefits. By keeping them for a long time, the good years more than even out the bad years, and you are almost guaranteed to make ~6-7%/year. Buying individual stocks is a really, really bad idea. If you aren't willing to invest the time to become an expert investor, then you will almost certainly do worse than index funds over the long run. Another option is to use your capital to start a side business (like your vending machine idea). As mentioned before, this still has risks. One of those risks is that it will take more work than you expect (who will find places for your vending machines? Who will fill them? Who will hire those who fill them? etc.). The great thing about an index fund is that it doesn't take work or research. However, if there are things that you want to do, that take capital, this can be a good way to make more income.
