If I can't admit I'm wrong or that I could have done something better, I can't improve.
I also can't take small losses before they become large ones.
The cultural model is to mercilessly attack and annihilate people who admit they made a mistake, were wrong or changed their mind.
Many view people who admit they are wrong as "weak" or wafflers.
The only way to improve as a trader and as a person is to admit to myself my mistakes and learn from them.
Obviously, I have to buck the cultural ego-based model of having to be right to succeed as a trader.
I also have to be honest with myself about my behavior.
How much has having to be "right" cost you in your trading career?
I REALLY don't know in my personal life cause I doubt I have ability to know what normal is in life in general. I am one who gets older and make even more mistakes in my life that when I was younger, but all who know me or friends, I laugh of the mistakes I do and often times broadcast them to show others that mistakes don't embarrass me but I embrace them as I have taken a risk, I don't look at mistakes as failures but an opportunity to do it again a different way.
In Business it is different, it has been huge losses of money, and at time they were not funny, but I find some of the idiot events that I have done are quite funny. I can't change them but have learned from them. Trading early on was good stock trader/investor, I have always wished I stayed doing that and never "tried" day trading, I lost seven great years in stock trading to overcome day trading. Lost over $100k learning about Commodities and have done well trading them, but the seven years of losing money but even worse finding all the horrible emotions I learned about myself I could have been happier never have learned. I had already know I had ADHD and bi-polar so I thought I knew how to deal with that and maybe because of that made me to preserver even more. But the constant being wrong meant losing money, losing time cause force me to take extra jobs beside full time job to pay my education. Less time to relax or vacations. I always knew why I was losing and why I was wrong, each having a different answer. I was losing cause I needed to learn how to program and back test, and why I was wrong.....too personal to answer.
You have to overcome lying to yourself.
At some point as a trader, you simple don't care what people think about you, they will never understand.
First 32 years it was not important to be "right", it was to make money trading and be consistent, NOW it is about being right, I feel I have been at this such a long time, I should be right, should be profitable and that is what I stride for on each trade. But I never bet the farm, I am not perfect, but often told I am a perfect A-hole, well, I have worked hard at being that as well. LOL
So you can be that person who stands up to the world at top of your lungs yell "I MADE A MISTAKE AND I AM PROUD THAT I TRIED AND WILL TRY AGAIN" or you can be the twerp sitting on the couch laughing at me cause I failed and they will never be truly happy.
