Mental Flexibility & Emotional Bravery

I liked this tweet because I like compliments and more importantly because it is insightful. Trading great Stan Druckenmiller talks about something similar when he says that open-mindedness is essential to success in the stock market. However, he also talks about "bravery" in overcoming emotions and in taking large bets when the odds are favourable. I struggle with the second trait more than the first.

I think a good way to test if you are falling into either trap of stubbornness or irrational fear is to discuss decisions with other knowledgeable investors, especially those with complementary personalities.
