Better is the end of a thing than the beginning thereof; And the patient in spirit is better than the proud in spirit.

Ecclesiastes 7:8
The same idea in other traditions
Pride goeth before destruction, and an haughty spirit before a fall.
So, verily, with every difficulty, there is relief: Verily, with every difficulty there is relief.
The Master said, "Specious words confound virtue. Want of forbearance in small matters confounds great plans."
A man is not learned because he talks much; he who is patient, free from hatred and fear, he is called learned.
By conquering anger he obtains patience; he acquires no Karman productive of anger, and destroys the Karman he had acquired before.
Give me the cup! a voice rings in mine ears / Crying: “Bear patiently the bitter years! / For all thine ills, I send thee heavenly grace. …
Let patience be your purpose in life; implant this within your being. In this way, you will grow into a great river; you will not break off into a tiny stream.
