Man needs difficulties; they are necessary for health.

Man needs his difficulties because they are necessary to enjoy success.

If a man needs his appendix taken out, his gallbladder treated and some brain surgery as well, I don't think too many doctors would do the jobs simultaneously.

This man needs to be thrown in a deep, dark hole and left to rot.
