Ecclesiastes 7:8-10

Amplified Bible

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.^(A)
10 
Do not say, “Why were the old days better than these?”
For it is not from wisdom that you ask about this.
