All our unhappiness comes from our inability to be alone. [ La Bruyère ]

Our happiness is but an unhappiness more or less consoled. [ Ducis ]

Present unhappiness is selfish; past sorrow is compassionate. [ Joseph Roux ]

Too much sensibility creates unhappiness; too much insensibility creates crime. [ Talleyrand ]

The happiness or unhappiness of men depends no less upon their dispositions than their fortunes. [ La Rochefoucauld ]

There is nothing in the world so much admired as a man who knows how to bear unhappiness with courage. [ Seneca ]

It is no happiness to live long, nor unhappiness to die soon; happy is he that hath lived long enough to die well. [ Quarles ]

Irresolution on the schemes of life which offer themselves to our choice, and inconstancy in pursuing them, are the greatest causes of all our unhappiness. [ Addison ]

Man's unhappiness, as I construe, comes of his greatness; it is because there is an Infinite in him, which, with all his cunning, he cannot quite bury under the finite. [ Carlyle ]

Another underlying condition of contentment is not to take one's self, or even the affairs of life, too seriously. In looking back, every one can see how much unhappiness has been derived from an over-weening sense of one's importance. [ Henry D. Chapin ]

The misery of human life is made up of large masses, each separated from the other by certain intervals. One year the death of a child; years after, a failure in trade; after another longer or shorter interval, a daughter may have married unhappily; in all - but the singularly unfortunate, the integral parts that compose the sum-total of the unhappiness of a man's life are easily counted and distinctly remembered. [ Coleridge ]
