DBB-111

But you, keep your head in all situations, endure hardship, do the work of an evangelist, discharge all the duties of your ministry. (2 Timothy 4:5)

Keeping one's head in all situations is easier said than done, but that's what the Apostle Paul asks young Timothy to do among other important things. 
Different Bible translations have interesting versions of the phrase (keep your head in all situations)
be sober in all things.....NASB
be calm and cool and steady....AMPLIFIED BIBLE
be clear-minded in all......GREEN'S LITERAL TRANSLATION
keep a clear head about everything....CHRISTIAN STANDARD BIBLE
watch thou in all things....KJV
be watchful in all things.....NKJV

We read of the Apostle himself losing his cool once, but he immediately realised it and corrected himself. It happened thus......
Then Paul, looking earnestly at the council, said, "Men and brethren, I have lived in all good conscience before God until this day." And the high priest Ananias commanded those who stood by him to strike him on the mouth. Then Paul said to him, "God will strike you, you whitewashed wall! For you sit to judge me according to the law, and do you command me to be struck contrary to the law?" And those who stood by said, "Do you revile God's high priest?"Then Paul said, "I did not know, brethren, that he was the high priest; for it is written, "You shall not speak evil of a ruler of your people."' (Acts 23:1-5)
 
Be sober, be calm and cool and steady, be clear minded, be watchful....keep your head in all situations......
Paul's exhortation is not only for Timothy, but for all of us who have put our trust in Jesus Christ. 
It may not work out always, but try we must, by fixing our eyes on Jesus and keeping the Apostle's exhortation in mind.
