1. People who suffer have no right to be pessimistic. If a suffering person is pessimistic, he will lose the courage to face the reality and the strength to fight against suffering. In this way, he will be more painful. (Nietzsche, Germany)

I'm only afraid of one thing: not worthy of my pain.

I'm only worried about one thing. I'm afraid I don't deserve my pain. (Dostoevsky)

People like to compare youth to spring, and this metaphor is correct. However, the similarity between the two is not so much that the sunshine of young people is like the sunshine of spring, but rather that from another side, the sadness and growth of young people are more like the spring that evolved in the cloudy wind, rain and cold. Because the latter is longer, heavier and more meaningful than the former. I often think of a painting called Spring by Van Gogh, a Dutch painter, in front of any young people: the background of the painting is several short and narrow houses, with a peach tree or apricot tree in the middle and a few pink flowers on its branches alone. I think, after a long time of wind and rain, this tree is still enduring the cold of late spring, surrounded by a poor world, but the juice of life is flowing in its branches. This is a real, boastless spring! Isn't it the same for young people? Life does not need to grow all the time, but it is not always the warm wind outside.

-Rilke wrote ten letters to a young poet.

There are also inspirational sentences that are a little old-fashioned:

The dream of 1 is still there. What if it comes true?

I walk slowly, but I never walk backwards.

Abraham lincoln

As long as you have tried flying, you will look up at the sky when you walk, because that's where you have been and you are eager to go back.

-Leonardo da Vinci
