This is a slightly different approach, but I would say openness and honesty is one way to practice humility if you’re a rather meek person like I am. Telling the truth about who you are is humility, because humility is having an accurate assessment of yourself not thinking you are greater or less than. So being honest about little stuff like:
telling my hairdresser I use box dye when I know she wouldn’t approve, and other situations when I’m afraid of disapproval.
Not exaggerating to make myself seem better than I am
Not making excuses about why I haven’t done something
Being honest about your motivation for doing things
Not saying you don’t care or it doesn’t matter if it does
Just my 2¢
