Many people seriously underestimate labor investment needed to achieve success in trading. As a result they are locked in a situation when years are already spent with no positive result, but admitting it as a loss to even diversify (find a job or like that) is hardly possible for them emotionally. Trading cost a divorce to one great trader who helped me so much in past...

I remember the Gorilla Game people at TMF back in late '99 and early '00. They believed fervently that what they called the "gorilla" stocks were well worth what was being asked, if not more. Even when it all began to unravel, they held on to the last. I tried explaining that there can be a vast difference between the value of a stock and the value of a company, but that for the most part fell on deaf ears. Eventually, some of those who listened thanked me, but most lost everything.
I now always says yes OK. First you need 200 hours with a qualified clinical psychiatrist. I never hear from them again.
It is true that there is a very thin line between trading and gambling. Without putting safeguards, one can easily fall into gambling.
