Ecclesiastes 7:9

Wisdom'Although Vulnerable'Is Beneficial

⁸
The end of a matter is better than its beginning;
Patience of spirit is better than haughtiness of spirit (pride).
⁹ 
Do not be eager in your heart to be angry,
For anger dwells in the heart of fools.
¹⁰
Do not say, “Why were the old days better than these?”
For it is not from wisdom that you ask about this.
