Rilke on Becoming an Artist and the Pursuit of Poetry
"Therefore, my dear sir, I know no advice for you save this: to go into yourself and test the deeps in which your life takes rise; at its source you will find the answer to the question whether you must create. Accept it, just as it sounds, without inquiring into it. Perhaps it will turn out 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 recompense might come from outside. For the creator must be a world for himself and find everything in himself and in Nature to whom he has attached himself.
But perhaps after this descent into yourself and into your inner solitude you will have to give up becoming a poet; (it is enough, as I have said, to feel that one could live without writing: then one must not attempt it at all). But even then this inward searching which I ask of you will not have been in vain. Your life will in any case find its own ways thence, and that they may be good, rich and wide I wish you more than I can say."
- Rainer Maria Rilke, 1903
