John Steinbeck said this quote
“ Do you know, I am putting off ending this letter as though the end would be the end of something I want to hold on to. That's not true of course - just a feeling like the quick one of hexing your trip so you couldn't go. The mind is capable of any selfishness and it thinks unworthy things whether you want it or not. Best to admit it is a bad child rather than to pretend it is always a good one. Because a bad child can improve but a good one is a liar and nothing can improve a liar. ”
