Is humility self-ignorance?

Am I humble when I underestimate what I'm capable of

Am I self-conceited when I overshoot that very capability?

Is it ignorance that guides me to be humble, is it in my humility that I seek

a confirmation that denies my ignorance, and once I get the 

validation, does it augment my humility or deny me the reality of self-ignorance?

Am I then self-conceited

Am I still then humble
