For the overseer must be above reproach as God’s steward, not self-willed, not quick-tempered, not addicted to wine, not pugnacious, not fond of sordid gain,
Titus 1:7 (emphasis mine)

To be self-willed is to be arrogant, stubborn, primarily concerned about one’s own interests or preferences.

Scripture requires that churches have a plurality of eldership so the church can benefit from the shared wisdom of godly men.

Where there is no guidance the people fall, but in abundance of counselors there is victory.
Proverbs 11:14

Without consultation, plans are frustrated, but with many counselors they succeed.
Proverbs 15:22

For by wise guidance you will wage war, and in abundance of counselors there is victory.
Proverbs 24:6

On the other hand, the Scriptures warn us about the one who always thinks he is right!

Do not be wise in your own eyes; fear the LORD and turn away from evil.
Proverbs 3:7

The way of a fool is right in his own eyes, but a wise man is he who listens to counsel.
Proverbs 12:15

A biblical elder must desire, first and foremost, to honor God in his own life as well as in the church. He will also desire to benefit from the wisdom of other godly men. His focus will not be on getting his own way. He will gladly yield his will to the collective wisdom of his fellow elders.
