The wise don't make a show of their knowledge,
 but fools broadcast their foolishness. — Proverbs 12:23

Wise people have a quiet confidence. Unstable people (fools) feel the need to prove themselves, but wise people don't have to prove anything. They know they are capable, so they can get on with their work.

Beware of showing off. If you are modest, people may not notice you at first, but they will respect you later.

God who looks at hearts does not like fake actors, but appreciates those who are pure in spirit.
Jesus Loves you!

( Tyndale)
