Does saying you're humble make you not humble?
Nope I'm humble and proud of it ;)
If you consider humility a good thing, then yes.
I think it depends on how you say it.
It's NEVER about the words .. It's ALWAYS about the actions
If saying you are humble is enough to knock you off balance than perhaps you are not humble enough to claim it. As they 'as above so below.' Same goes for pride. Buddha will tell you to take the middle way.
