sure of oneself

And though I was entering my marriage as she was exiting hers, I felt that our joy came from a similar place: of being in the right place, at the right time, sure of oneself.

One has to be very strong and very sure of oneself to go against the ordinary view of things.

One is as sure of oneself as a woman of thirty, and with as much and as little reason.

The vertigo of life produces itself like the vertigo of heights, when one is not sure of oneself.

One should choose the time when the audience is not yet fully arrived, since, unless one is very sure of oneself, it is a risky matter to appear upon the scene when the house is full, or the guests for the most part assembled.
