Expectation is about action, while anticipation is about results. Increasing our expectations for something fuels our motivation to act, but at the same time, lowering our anticipations helps reduce the sense of disappointment.
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.
I think the scenario you are putting into your explanation doesn't speak for all situations. Your expectations can only becomes action when it is you to do the action. There are other instances where you only have to anticipate and also expect. Take Bitcoin as a case study, if you buy Bitcoin today, you anticipate for it to grow and that's require your patience but the expectations will be there as well but you can't do anything about it since you don't determine the price.
In anything you do, be optimistic and anticipate but don't let your expectations be high about it because life is all about changes, because something does happen doesn't mean it will happen all the time. Nobody expect corona virus to disrupt the market in 2020 and it came, anyone with high expectations of making millions under those period before the disaster will be affected and same thing can happen in other scenarios.
