1. I believe it is correct to say "He who has a why to live can bear almost any how". By having a reason to live a person, can overcome any hardships which they may have to live. A reason to live, whatever it may be pushes a person to strive forward in his or her life. It offers a goal for that person to achieve and in the process it promotes perseverance. This will is …

…something to live for work through their imprisonment as a means to a better end. It can also be witnessed in terminally ill patients who miraculously recover.

Thus it is correct to say "He who has a why to live can bear almost any how", because the strength and fortitude of the human soul can outlast any pains.
