It is fine to invest whether it guarantees you to be wealthy or not. The worst thing that could happen is that you didn't invest at all because of fear of not getting rich through investment.
In everything in life, there is an iota of risk attached to it.
People that are willing to take such risks are the people that are always the rich ones. This kind of post in Op encourages laziness and fear of breaking through your comfort zone.
My only advice is anyone investing should have a good knowledge of whatever they are investing in. A good investment can make a difference in your life while a bad investment can ruin your chances of becoming wealthy.
This statement you made reminds me of something my friend said some years ago, and every time he sees me, he always regrets not taking the decisions I convinced him to make then. Although it's not too late for him to start, but he's so weak.
Look what happened: he chose me as a friend, but in him, I never had a friend because he had no good visions or goals for his life, and I noticed It would just be a kind of parasitic relationship between us, so I just kept the relationship neutral. After my graduation from the university, I was just working on a few things (jobs and hustles) to help me build my business, but at some point I travelled to my home town, and this friend was just sitting at home all day long, visiting friends and playing games. Although he gambles a little bit, it's not that hard because he's got no money to even spend on gambling. He was just wasting his time for nothing. So, I advised the guy to invest in Bitcoin and hold it for a few years, and he will make some profit to start up something, but he said he's got no money to invest in Bitcoin, and I told him that apart from Bitcoin, he can invest in other things or possibly invest in himself instead of wasting his time every day sitting at home doing nothing, but this guy was not positive. I offered to let him stay in the city so he could get a job, save up some money, and do something meaningful for himself. It was then that I made a statement by telling him to "leave his comfort zone", but his response freaked me out; he said even other people have a better comfort zone where they are so comfortable eating and drinking (living good life), but that what I see as a comfort zone is not really a comfort zone for him. He said he was facing hell in his comfort zone, but I still advise him that since home is not a comfort zone for him, he should take the challenge to leave home and come to the city where he can get a job. He was adamant; time travelled so fast, and we have crossed almost four years now since I gave him the advice. He is aware of every price of Bitcoin since 2020 to date, but he has not invested because he has no money to do so.
So, based on the OP, even before someone can be rich, they must be rich in their thoughts (mindset). My friend had a poor mindset, and I believe that even if he had taken my advice to invest, that would not have guaranteed his success because his mind is not made up to be successful. Someone once said that "to become successful, you will try and fail for some time before you can actually become successful at the end." So, someone who is not ready to let go of their past failure will not be successful; someone who cannot rise up after they fail will not be successful. Someone who is not prepared for success will never see it because success comes with a lot of obstacles.
@rby, Based on what you've said, I agree with you.
