Separating the two words 'humility and teachable' brings another meaning to your thread as I'm on the side of traders been willing to learn form their mistakes (i.e taking corrections) and improving on themselves to becoming a better trader but don't totally buy into the idea of been humble. The market has no emotions and shouldn't be approach with a mindset of trying to win it over with humility instead been smart, having the mindset to outsmart the market at any movement it tries to make will make you more profitable.
In regards to pride and arrogant, don't actually get where you're heading but if you mean not been willing to adopt to new development or changes instead sticking to your old ways that obvious should new an outdated then that's a wrong mindset that will only result to loses.
