Contrary to all those times you've heard a writer confess at a reading that he writes fiction because he is a pathological liar, fiction writing is all about telling the truth.

The silver lining of those years when I was trying to get 'Tinkers' published but couldn't were the years when I had to decide, Why do I want to be a writer? I realized that writing is the thing itself; writing is not a means to publication, writing is not a predicate of publication, so I spent years making art for art's sake.

I was just delighted to be a legitimate, for-real published author.

Write as precisely and as lucidly and as richly as you can about what you find truly mysterious and irreducible about human experience, and not obscurely about what will prove to be received opinion or cliche once the reader figures out your stylistic conceit. There's all the difference in the world between mystery and mystification.
