What makes a lot of trader run at loss is because they don't appreciate the little profit that they made from trading. Instead, they want more and that will make them not close their position when they have seen little profit but leave it open and before you know it, they will get liquidated. This is why you should be satisfied with little profits.
Such traders are only concerned with big profits and are more greedy,
whereas when a little profit is made frequently then it will also result in big profits in the end.
People who focus too much on big profits don't think about the risk of losing that they are not aware of.
When the loss occurs, the decline becomes worse, they will sell at a low price and get a miserable loss.
