Bill Bryson Quotes
What this means in practice is that if you are not a born worrier you have nothing to worry about (though of course you wouldn't be worrying anyway), whereas if you are a worrier by nature there is absolutely nothing you can do about it, so you may as well stop worrying, except of course you can't.
