Rejecting involves rebuffing, repudiating, repulsing, repelling, and refusing. When we reject, we dismiss, deny, or disavow something because it is inadequate, faulty, wrong, unacceptable, or just plain evil.
Some things require little work and can be dismissed out of hand. However, for other things, rejection is inadequate. More is required.
Things that cannot be rejected must be overcome -- meaning that they must be dealt with and gotten the better of.
Our primary purpose is not to reject the world but to learn from it and strive to overcome it.
And that makes all the difference in the world.
