Let's be brutally honest for a minute. Before we learned about risk management and realistic expectations (usually by losing a painful amount of money), we were all a little bit insane.
We all had that one beautifully stupid belief that we thought was our ticket to a Lambo.
When you are newbies, you can start trading and think you are a genius trader in this market. It is a first terrible mistake and next ones are: use all money you have for trading, make loan for trading, trade with leverages or futures type, and say no with Stop loss order in your trading.
All of those mistakes are very popular among newbies while they actually should not trade and must use stop loss order to defend their initial trading capital as best as possible.
