Why you keep losing money with trading?

Why do really successful traders never share their methods or strategies?

Why do many people in trading study Taoist or Buddhist theories?

I have had a few positions liquidated recently, but fortunately the losses were not very large. I would like to ask everyone, is there any way to prevent liquidation? Is there any trading discipline?

As a "trader", what trading discipline do you have to restrain yourself?

If you want to make money in trading, what principles do you need to understand?
