Without patience, we will learn less in life. We will see less. We will feel less. We will hear less. Ironically, rush and more usually mean less. - Mother Teresa

Smiling novices. I can hear the music of your laughter of joy. Learn, my children, to be holy, for true holiness consists of doing God's work with a smile.

It is our emptiness and lowliness that God needs and not our plenitude. These are a few of the ways we can practice humility:
Speak as little as possible of oneself.
Mind one's own business.
Avoid curiosity.
Do not want to manage other people's affairs.
Accept contradiction and correction cheerfully.
Pass over the mistakes of others.
Accept blame when innocent.
Yield to the will of others.
Accept insults and injuries.
Accept being slighted, forgotten, and disliked.
Be kind and gentle even under provocation.
Do not seek to be specially loved and admired.
Never stand on one's dignity.
Yield in discussion even when one is right.
Choose always the hardest.

Sincerity is humility, and you acquire humility only by accepting humiliations.
