give oneself away

One must strive with one's whole strength to give oneself away.

I am not speaking of things obviously wrong, cruel, unkind, ungenerous, spiteful things; but it is right to give oneself away, to yield to impulses, not to take advice too much, and not to calculate consequences too much.

One has to be so frightfully careful not to give oneself away when one knows everything.

It seems that the Polish characteristic is to lend oneself, but never to give oneself away, and one of Chopin's friends said of him that he was "more Polish than Poland itself."

It is heaven on earth to love and to give oneself away.
