Investing can be seen as having a higher chance of success compared to starting a business, because you're putting your money into companies with stronger competitive advantages. However, whether you're investing or starting a business, you need to accept that you might lose that money the moment you put it in. Put in 100% effort, but don’t get too caught up in fantasies. The outcome will be a natural result of your hard work.
Investing can come in many forms, you can invest your time with potentially minimal expenses to grow some businesses from an early stage. You mention investing in business like it is guaranteed success, but this is not true - many medium/large businesses will eventually decline slowly or even implode rather quickly, so you have to do your homework to make sure your share of invested money does not shrink towards zero. There is definitely truth in your reference to anticipation though, many people still think that "investing" is about doubling your money overnight, or even over the course of one year, but that is simply unrealistic and would lead you down a path of much riskier companies which is likely to fail long term.
