Why is this so hard? There are a million ways to make money, but more like a zillion ways to lose money.
It takes money to make money. Thus, capital is a limited resource. If it doesn't add up, then it is be being taken away. And it doesn't take too much of those take aways to completely blow an account.
It would take me a day to blow 40K, and would take me a year to make 40K.
Lets get it straight, it is EASY to lose money, even if you try to lose money because markets are set up to lose money.
