Investing is probably dumb

I told my son to learn as much as he can about stocks and dividends.
Having a 401(k) probably is the shadiest legal means to save for retirement. How many people actually know what they're doing? I don't exactly, but I look at what's offered and play with the ups and downs.
Risk management means trying to not lose more than what you put in beyond whatever is being matched by an employer.
It's impossible to time the market, so greed can be a good thing or a bad thing based on timing.
I have a hard time cutting my losses. I tend double down and wait for a bounce back to recoup some of  my losses. Patience is a virtue  that seems to be better served via a system than gut instinct. There's simply too much emotion involved. Emotion impairs decision making.
