Is financial trading a profession?

In the past few months, I feel that the more I study, the more I study, but it will decline. Sometimes I feel conflicted. I don’t know why?

If you have a bad mentality, does this mean that you are not suitable for trading?

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?

Traders, what moments do you feel "really broke"?

Why can you see the general direction right, but make a bad point in the transaction, and lose money instead?
