Humble: Being humble is the key to life. You arnt showing off as always and bragging about your rich life and you take it for granted and think your always rich and all that and your the best.
Even if you are 'the best' in the world at doing one thing, there are always other things that you cannot do, and may never be able to do.

Recognizing your limitations does not mean abandoning your dreams, and it does not mean giving up on learning new things or improving your existing abilities. It simply means acknowledging that, as human beings, none of us are perfect and none of us can do everything by ourselves.It's okay to have a healthy self-esteem and to feel proud of your accomplishments, but nobody likes it when someone constantly tries to bring attention to themselves and their own achievements. If you feel like you really have done something great, chances are people will have already begun to notice that, and they will come to respect you even more for your humility.
