The biggest problem with trading is unrealistic expectations.

If people believed they could become a medical doctor by taking a weekend boot camp, you would see extremely high failure rates.

But that high failure rate would not suggest that it’s impossible to become a doctor.

Same with trading, if a person thinks they will make a few trades as their side hobby, it’s going to go about as well as the hobbyist surgeon. But if you’re obsessed with trading for a decade you can become quite competent.
