Not at all, because discipline comes naturally when you KNOW (from the backtest) that your purely mechanical trading system is highly profitable. The most undisciplined traders are always the ones who have no clue what they are doing.
The so called logic and analytical skills are overrated. Both in the market and in real life. You just cannot know everything, every single variable. The latter means there is no such thing as truly sound logic but an illusion, an assumption.
The seemingly not important variables make or brake wealth. Not a fan of the sassy Lebanese guy but Black Swan / Antifragile is a must for most young traders/investors. Way to many things considered common knowledge are not that common anymore. A lot of them are replaced by "logic". Whatever... do your magic.
Funny OP and actually true. Probably going to elicit some hurt feelings, though. In the sense that markets are predictable, so are people. Even EliteTraders. LOL.
You don't like women very much, do you? There are plenty of useless threads and informations online in this shallow social media infested world. This is one of them.
The important variables are what determine your wealth. Look at your life. I bet you have 2 or 3 decision points that would have or actually have defined your wealth today. for taleb it was probably figuring out that writing books was more profitable than actually buying those tiny options.
