My only advice for you is this. Go within yourself and probe the depths 
from which your life springs, and there at its source you'll find the 
answer to the question of whether you must write. Accept this answer, 
just as you hear it, without hesitation. It may be revealed that you are
 called to be an artist. Then take this lot upon you, and bear it, its 
burden and its greatness, without asking for any external reward. For 
the creative artist must be a world for himself, and find everything 
within himself—and in nature, to which he is devoted.
Rainer Maria Rilke
