In a way, the themes of writing and of solitude in Letters to a Young Poet are intertwined: advice for the latter is mostly in regard to the former, and any advice for the former includes some of the latter. But I tried extricating them the best that I could because there is something to be gained from each, so below are some excerpts of Rilke’s advice on how to become a good writer.
After asking ourselves whether we have to write or not, we should then write out of that necessity rather than for praise or for anyone else. There is always enough material in life for our art as long as we are creating it out of a compulsion to create, as long as we are digging into ourselves and our worlds and not seeking outside compensation:
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, as if no one had ever tried before, try to say what you see and feel and love and lose. Don’t write love poems; avoid those forms that are too facile and ordinary: they are the hardest to work with, and it takes a great, fully ripened power to create something individual where good, even glorious, traditions exist in abundance. 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, and 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 no poverty and no poor, indifferent place. And even if you found yourself in some prison, whose walls let in none of the world’s sound – wouldn’t you still have your childhood, that jewel beyond all price, that treasure house of memories? Turn your attention to it. Try to raise up the sunken feelings of this enormous past; your personality will grow stronger, your solitude will expand and become a place where you can live in the twilight, where the noise of other people passes by, far in the distance. And if out of this turning within, out of this immersion in your own world, poems come, then you will not think of asking anyone whether they are good or not. Nor will you try to interest magazines in these works: for you will see them as your dear natural possession, a piece of your life, a voice from it. A work of art is good if it has arisen out of necessity. That is the only way one can judge it. So, dear Sir, I can’t give you any advice but this: to go into yourself and see how deep the place is from which your life flows; at its source you will find the answer to the question of whether you must create. Accept that answer, just as it is given to you, without trying to interpret it. Perhaps you will discover that you are called to be an artist. Then take that destiny upon yourself, and bear it, its burden and its greatness, without ever asking what reward might come from outside. For the creator must be a world for himself and must find everything in himself and in Nature, to whom his whole life is devoted.
Again, he reiterates that outside opinions should not shape our art or writing and that allowing life to compost inside of us and to come out when it’s ready is the best way to stay genuine and sincere in what we do:
But let me make this request right away: Read as little as possible of literary criticism. Such things are either partisan opinions, which have become petrified and meaningless, hardened and empty of life, or else they are clever word-games, in which one view wins, and tomorrow the opposite view. Works of art are of an infinite solitude, and no means of approach is so useless as criticism. Only love can touch and hold them and be fair to them. Always trust yourself and your own feeling, as opposed to argumentation, discussions, or introductions of that sort; if it turns out that you are wrong, then the natural growth of your inner life will eventually guide you to other insights. Allow your judgments their own silent, undisturbed development, which, like all progress, must come from deep within and cannot be forced or hastened. Everything is gestation and then birthing. To let each impression and each embryo of a feeling come to completion, entirely in itself, in the dark, in the unsayable, the unconscious, beyond the reach of one’s own understanding, and with deep humility and patience to wait for the hour when a new clarity is born: this alone is what it means to live as an artist: in understanding as in creating.
In this there is no measuring with time, a year doesn’t matter, and ten years are nothing. Being an artist means: not numbering and counting, but ripening like a tree, which doesn’t force its sap, and stands confidently in the storms of spring, not afraid that afterward summer may not come. It does come. But it comes only to those who are patient, who are there as if eternity lay before them, so unconcernedly silent and vast. I learn it every day of my life, learn it with pain I am grateful for: patience is everything!
So, while we should be wary of literary criticism, doubt can be a useful tool in our writing and artistic repertoire as long as we train it. This is one of my favorite passages on training the critical eye to be helpful and productive rather than destructive:
And your doubt can become a good quality if you train it. It must become knowing, it must become criticism. Ask it, whenever it wants to spoil something for you, why something is ugly, demand proofs from it, test it, and you will find it perhaps bewildered and embarrassed, perhaps also protesting. But don’t give in, insist on arguments, and act in this way, attentive and persistent, every single time, and the day will come when, instead of being a destroyer, it will become one of your best workers – perhaps the most intelligent of all the ones that are building your life.
