On proper training to become a Dragonfly. Below is an excerpt.
Do not underestimate the difficulty of becoming a Dragonfly. Dancing well consistently is an exceptional skill of analytic prowess, emotional cool, and reflexive decision-making.
The bets you considered and did not make are as telling as the ones you did. 99% of time you spend “in the market” is as an observer. The skill of dancing is picking the perfect 1%.
To transform into a Dragonfly, train in the simulator until 90%+ of your investments are profitable and losing positions are instantly abandoned. On days when the market offers good trading opportunity density, you should be averaging 2% to 5% return on stake, around 1% on mostly-sideways sessions, and sagely staying out when the market is chaotic.

For any ambition of any significance, you must have patience and persistence. Becoming a Dragonfly is a great ambition. Embrace it wholeheartedly. The purpose should not be making money: that is only the outcome. The purpose of Dragonfly is mastery of your mind. Dancing is an epitome of mental skill: to consistently assess a complex fast-moving dynamic and successfully anticipate movement vectors. Someone who can do that deserves to mint money.
