Now for more than five years already, I do not know exactly how long, I'm more or less without employment, wandering here and there.. .But you will ask what is your definite aim? That aim becomes more definite, will stand out slowly and surely, as the rough draft becomes a sketch and the sketch becomes a picture.. .. my only anxiety is: how can I be of use in the world, cannot I serve some purpose and be of any good, how can I learn more and study profoundly certain subjects?
