Excerpt from Nick Hornby's A Long Way Down:

We all spend so much time not saying what we want, because we know we can't have it. And because it sounds ungracious, or ungrateful, or disloyal, or childish, or banal. Or because we're so desperate to pretend that things are OK, really, that confessing to ourselves they're not looks like a bad move. Go on, say what you want. Maybe not out loud, if it's going to get you in trouble: "I wish I'd never married him." "I wish she was still alive." "I wish I'd never had kids with her." "I wish I had a whole shitload of money." "I wish all the Albanians would go back to fucking Albania." Whatever it is, say it to yourself. The truth will set you free. Either that or it'll get you a punch in the nose. Surviving in whatever life you're living means lying, and lying corrodes the soul, so take a break from the lies for just one minute.
