Be patient towards all that is unsolved in your heart and try to love the questions themselves. Live the questions now. Perhaps you will find them gradually, without noticing it, live along some distant day into the answer.
It is also good to love: because love is difficult. For one human being to love another human being: that is perhaps the most difficult task that has been entrusted to us, the ultimate task, the final test and proof, the work for which all other work is merely preparation. (43)
A work of art is beautiful if it has arisen out of necessity. (11)
...for ultimately, and precisely in the deepest and most important matters, we are unspeakably alone; and many things must happen, many things must go right, a whole constellation of events must be fulfilled for one human being to successfully advise or help one another.(14)
And in fact the artist's experience lies so unbelievably close to the sexual, to its pain and its pleasure, that the two phenomena are really just different forms of the one and the same longing and bliss. (19)
We must accept our reality as vastly as we possibly can; everything, even the unprecedented, must be possible within it. This is in the end the only kind of courage that is required of us: the courage to face the strangest, most unusual, most inexplicable experiences that can meet us. (52)
There is only one thing you should do. Go into yourself. Find out the reason that commands you to write; see whether it has spread its roots into the very depths of your heart; confess to yourself whether you would have to die if you were forbidden to write. This most of all: ask yourself in the most silent hour of your night: must I write? Dig into yourself for a deep answer. And if this answer rings out in assent, if you meet this solemn question with a strong, simple "I must," then build your life in accordance with this necessity; your whole life, even into its humblest and most indifferent hour, must become a sign and witness to this impulse. Then come close to Nature. Then, as if no one had ever tried before, try to say what you see and feel and love and lose.
So rescue yourself from these general themes and write about what your everyday life offers you; describe your sorrows and desires, the thoughts that pass through your mind and your belief in some kind of beauty--describe all these with heartfelt, silent, humble sincerity and, when you express yourself, use the things around you, the images from your dreams, the objects that you remember. If your everyday life seems poor, don't blame it; blame yourself; admit to yourself that you are not enough of a poet to call forth its riches; because for the creator there is not poverty and no poor, indifferent place.
You are so young, so much before all beginning, and I would like to beg you, dear Sir, as well as I can, to have patience with everything unresolved in your heart and to try to love the questions themselves as if they were locked rooms or books written in a very foreign language. Don't search for the answers, which could not be given to you now, because you would not be able to live them. And the point is, to live everything. Live the questions now. Perhaps then, someday far in the future, you will gradually, without even noticing it, live your way into the answer. p. 24
...but take whatever comes, with great trust, and as long as it comes out of your will, out of some need of your innermost self, then take it upon yourself, and don't hate anything. Sex is difficult; yes. But those tasks that have been entrusted to us are difficult; almost everything serious is difficult; and everything is serious. (24)
But the fear of the inexplicable has not only impoverished the reality of the individual; it has also narrowed the relationship between one human being and another, which has as it were been lifted out of the riverbed of infinite possibilities and set down in a fallow place on the bank, where nothing happens. (52)
We have no reason to harbor any mistrust against our world, for it is not against us. If it has terrors, they are our terrors; if it has abysses, these abysses belong to us; if there are dangers, we must try to love them. And if only we arrange our life in accordance with the principle which tells us that we must always trust in the difficult, then what now appears to us as the most alien will become our most intimate and trusted experience. (54)
Don't observe yourself too closely. Don't be too quick to draw conclusions from what happens to you; simply let it happen. Otherwise it will be too easy for you to look with blame (that is: morally) at your past, which naturally has a share in everything that now meets you. But whatever errors, wishes, and yearnings of your boyhood are operating in you now are not what you remember and condemn. The extraordinary circumstances of a solitary and helpless childhood are so difficult, so complicated, surrendered to so many influences and at the same time so cut off from all real connection with life that, where a vice enters it, one may not simply call it a vice. One must be so careful with names anyway; it is so often the name of an offense that a life shatters upon, not the nameless and personal action itself, which was perhaps a quite definite necessity of that life and could have been absorbed by it without any trouble.
