sure of oneself

Certain of abilities

Confident in one's own abilities, judgment, or worth.

Someone sure of oneself acts without hesitation or self-doubt: She walked into the interview sure of herself.

The phrase can suggest healthy confidence or tip toward arrogance, depending on context: He's a little too sure of himself for my taste.
