Pain in life is inevitable but suffering is not. Pain is what the world does to you, suffering is what you do to yourself [by the way you think about the 'pain' you receive]. Pain is inevitable, suffering is optional. [You can always be grateful that the pain is not worse in quality, quantity, frequency, duration, etc]
But if you do not find an intelligent companion, a wise and well-behaved person going the same way as yourself, then go on your way alone, like a king abandoning a conquered kingdom, or like a great elephant in the deep forest.
When a man is stimulated by his own thoughts, full of desire and dwelling on what is attractive, his craving increases even more. He is making the fetter even stronger. But he who takes pleasure in stilling his thoughts, practising the contemplation of what is repulsive, and remaining recollected, now he will make an end of craving, he will snap the bonds of Mara. His aim is accomplished, he is without fear, rid of craving and without stain. He has removed the arrows of changing existence. This is his last body.
Not merely by rules of conduct and religious observances, nor by much learning either, nor even by attainment of concentration, nor by sleeping alone, do I reach the happiness of freedom, to which no worldlings attain. If you have not put an end to compulsions, nurse your faith
Evil-doers who denounce the wise resemble a person who spits against the sky; the spittle will never reach the sky, but comes down on himself. Evil-doers again resemble a man who stirs the dust against the wind; the dust is never raised without doing him injury. Thus, the wise will never be hurt, but the curse is sure to destroy the evil-doers themselves.
There is a way to be purified, to overcome sorrows and grief, to release suffering, to secure the right path to realize nirvana. This is to be mindful.
