We can know what we do wrong even before we do it,....

“ We can know what we do wrong even before we do it, but self-knowledge can't affect or change the outcome, can it? Everyone singing his own little song, convinced it's the most wonderful song the world has ever heard. Don't you see? We create our own thorns, and never stop to count the cost. All we can do is suffer the pain, and tell ourselves it was well worth it. ”

Colleen McCullough
