reconcile oneself

One took a long time to reconcile oneself to this idea, even when no hope of real success remained.

It's hard to reconcile oneself to taking this so easily, but I suppose it's the only thing to do.

One is sure always of being the dupe of something, and it may be better, perhaps, to reconcile oneself to the fact in advance.

That, of course, was one of the sad things of life to which one must reconcile oneself.
