Patience

Endeavor to be patient in supporting the defects and infirmities of others, of what kind soever; because thou also hast many things which others must bear withal.

If thou canst not make thyself such a one as thou wouldst, how canst thou expect to have another according to thy liking?

We would willingly have others perfect, and yet we mend not our own defects.

-- Imitation of Christ
