I totally agree with you, being humble in life has gotten some people to the place they are today, the position that some people are today is as a result of being humble, and being humble also bring you some kind opportunity dat even if u work for it, you won't earn it but being humble will get u there and just like u say, don't be so humble to the extent of being used for other people selfish desire or other people benefits because there are some people who takes other people loyalty for granted. So be humble and wise also smart in doing things with people to avoid being used and also focused in anything you are doing in life.
