No offense taken but it sure ain't me. I'm recent

No offense taken but it sure ain't me. I'm recently retired but worked in health care for 30 years and made a very good living. But it was no where near the income this couple had. My "friend" would often trade my yearly income on a regular basis. My point was, if an intelligent person with that amount of available cash, and the interest to go to courses and study the trading concepts, and the time to watch it practically minute by minute through the day couldn't actually make it work on a long term basis then I look at any claim of successful day trading/market timing with major skepticism.
