Someone frustrates us and the anger starts to boil immediately, and when that happens let us remember what Solomon said,

The end of a thing is better than its beginning;
The patient in spirit is better than the proud in spirit.
Do not hasten in your spirit to be angry,
For anger rests in the bosom of fools.
(Ecclesiastes 7:8–9)

Watch and discover who gets angry quickly, and you will learn what Solomon spoke is the truth, that the fool becomes angry, because he was not patient, not willing to wait for the end of a thing to see how it would turn out.
