I say this because a proud and arrogant trader to the market, will have a trouble looming ahead trading because over confidence in trading leads to losses.
Also, arrogance and pride while trading is the beginning of endless losses.
In as much as there's some point in your write-up, i believe to trade profitably, one needs to gather up some confidence as well some risk taking habit because trading favours those you are not afraid to face the market limitations. However, overconfidence and taking of uncalculated risk kills too because investments in a volatile market demands requires one to really use spare cash or cash which a person can afford to lose amd when a person is being overconfident, he can't really differentiate between blind risk and calculated risks.
