The biggest mistake of a trader is that you are on an unclear path, with no destination, vague, and uncertain about where you are.
It may be because you learn from those around you. You think they are better and successful when they traded a few months or a few years before you; they show you some of their profits. Learning from those who are worse always yields poorer or similar results.
You should learn from Mr. Market.
Mr. Market is my teacher. I have been trading for 6 years and have become a professional investor in all fields: gold, oil, forex, stocks, real estate, crypto, and even investing in the largest pharmaceutical companies in Vietnam. I have approved projects worth hundreds of billions of USD.
What you learn daily means nothing to me. It's not that I underestimate you. What I look down on here is the knowledge you have acquired. The terrible things you think are the holy grail, applied to daily trading.
If you know how to listen and think, investigate, you will see that the version of yourself is very wrong.
