The difference between who you want to be and who you are is humbling.
The recipe for humble pie requires good, clear eyesight.
And you need a reliable mirror that only shows the flaws in the reflected image, not in the mirror itself.
And you need to look at every detail in the whole of you. Even the secret things that you tend to conceal from everybody, especially yourself.
And writing a novel, if you do it right, is a form of baking humble pie.
The good and the not-so-good is reflected in reviews, which are often written with mirrors that have flaws.
But what you see, if you are honest with yourself, can show you that, even though you are far from perfect, you are exactly what you are supposed to be.
