To draw an analogy: a man's suffering is similar to the behavior of a gas. If a certain quantity of gas is pumped into an empty chamber, it will fill the chamber completely and evenly, no matter how big the chamber. Thus suffering completely fills the human soul and conscious mind, no matter whether the suffering is great or little. Therefore the "size" of human suffering is absolutely relative.

The one thing you can't take away from me is the way I choose to respond to what you do to me.

No one can become fully aware of the very essence of another human being unless he loves him.

Such a value system might be responsible for the fact that the burden of unavoidable unhappiness is increased by unhappiness about being unhappy.

When a man cannot find meaning, he numbs himself with pleasure.

The point is not what we expect from life, but rather what life expects from us.

It is here that we encounter the central theme of existentialism: to live is to suffer, to survive is to find meaning in the suffering.
