I get it. I have my own experiences, often expensive ones, behind the points I made above. And I was pretty angry and bitter about some of the things I was stung by, including short attacks. But I think that attitude interferes with your ability to learn lessons from your experiences. Rather than feeling angry and powerless, try to look for warning signs you could have spotted. Or trading patterns that amplified your losses. Did you hold longer than you should have? Did you then sell after the damage was done? Did you miss the recovery? Did you average down while the company crashed, like I did with Arrium to the tune of $20k?

It can be difficult to think about these things because some of it comes down to character flaws. For me... a massive level of arrogance. I refused to accept that I could be wrong, so I held on with "diamond hands". I was one of "the faithful", a "true believer", courageous no matter how violently the "tree-shake" was. I thought that "you only lose when you sell". But these are all phrases and beliefs for blaming things you can't control. Meanwhile you will miss the opportunity to learn how to recognise those situations and handle them better.

A good mentor who can help you face yourself honestly will save you a fortune.
