Fomo is what underlies their desire to get involved in trading, hoping to achieve large profits and get rich quickly, like the people they see.
Social media and the internet are indeed very influential, and they often adopt what they see as a standard of living, serving as an example, but with little chance of learning from it.
What you say is true: if they can pursue it diligently, they might also succeed, but it will certainly require a more complex and difficult process. A healthy mindset should help prevent them from misguided goals from the start.
The process might be complex and hard for them. But if they're persistent and serious about it, I think at some point they'll be able to make it.
But if they're just random traders that think it's a way to get rich without proper planning. They're only wasting their time and money in it.
Because the successful traders are existing but they went for a long process of failures before they're able to reach that.
Basically, any form of success isn't as easy as you might imagine, so it's perfectly natural that the process is difficult and complicated; this is part of the requirements for achieving success.
Anything done without the right intention and hard work, and based solely on hopes and dreams, will never succeed. As you said, they will ultimately just waste a lot of money and time. This is a fact.
Therefore, to achieve success in any field, one must work very hard, be disciplined, consistent, patient, and have a strong mentality.
