Whoever you are, no matter how lonely; the world offers itself to your imagination...

“You do not have to be good.
You do not have to walk on your knees
for a hundred miles through the desert, repenting.
You only have to let the soft animal of your body
love what it loves.
Tell me about despair, yours, and I will tell you mine.
Meanwhile the world goes on.
Meanwhile the sun and the clear pebbles of the rain
are moving across the landscapes,
over the prairies and the deep trees,
the mountains and the rivers.
Meanwhile the wild geese, high in the clean blue air,
are heading home again.
Whoever you are, no matter how lonely,
the world offers itself to your imagination,
calls to you like the wild geese, harsh and exciting –
over and over announcing your place
in the family of things.”
― Mary Oliver

Writing advice that helps answer the question....

... that great question of "what should I do with my life."

“You don't take on subject matter because of an objective sense that one sort of subject matter is more important than something else. You take on what you can handle, what you can transform, what you can make your own, what you can make explicable and clear to somebody else, the reader who might stumble across the poem and recognize his or her life in that cloudy mirror.” -- William Matthews
