I heed not that my earthly lot Hath - little of Earth in it - That years of love have been forgot In the hatred of a minute: - I mourn not that the desolate Are happier, sweet, than I, But that you sorrow for my fate Who am a passer by.
In the first place, you shouldn't believe in promises. The world is full of them: the promises of riches, of eternal salvation, of infinite love. Some people think they can promise anything, others accept whatever seems to guarantee better days ahead, as, I suspect is your case. Those who make promises they don't keep end up powerless and frustrated, and exactly the fate awaits those who believe promises.
Ah Fate, cannot a man Be wise without a beard? East, West, from Beer to Dan, Say, was it never heard That wisdom might in youth be gotten, Or wit be ripe before 't was rotten?
Now the pessimist proper is the most modest of men. ... under no circumstances does he presume to imagine that he, a mere unit of pain, can in any degree change or soften the remorseless words of fate.
If the whole responsibility is thrown upon our own shoulders, we shall be at our highest and best; when we have nobody to grope towards, no devil to lay our blame upon, no Personal God to carry our burdens, when we are alone responsible, then we shall rise to our highest and best. I am responsible for my fate, I am the bringer of good unto myself, I am the bringer of evil.
Humanity is our common lot. All men are made of the same clay. There is no difference, at least here on Earth, in the fate assigned to us. We come of the same void, inhabit the same flesh, are dissolved in the same ashes. But ignorance infecting the human substance turns it black, and that incurable blackness, gaining possession of the soul, becomes Evil.
