He taught you a good lesson. Appreciating yourself for your qualities is very good. Without being arrogant of course. A lot of people fear about standing proud for what they excel at out of fear. What if people will envy me or think that I am playing the superior role? Haters will hate and we should not impair our progress and diminish our achievements. Success is not comfortable to acquire but I would take it anyday instead of passively sitting on the side and criticizing others. Like the naysayers and non achievers do.
