People Who Build Trading Systems Are Emotionless

Once you truly build a trading system, and once you truly enter stable profitability, the joy that comes from the act of making money itself simply doesn't exist. Because you default to assuming that all the money on this street was yours to begin with.

Now that you own the whole street, it also means you bear responsibility. You can't keep stripping it bare the way retail traders do—you need fallow periods, you need restraint. Sometimes, after winning for too long, you even have to intentionally lose a little back, colloquially known as "bailing out the market." Otherwise, if you keep winning, everyone else will lose all hope of playing, and it becomes boring. No one wants to play anymore.

Furthermore, it's not that your mindset arrives first and then your profitability follows—it's the other way around. Your profitability has to arrive first so that your mindset can catch up. (This "arrival" means doubling your capital through investment, or even scaling it 100-fold.)

Only when those who have made money never think about leaving, and always stay in the market, forming value anchors and establishing wealth-defining authority—is the design model itself the ultimate form of investment.
