"Happiness is always a by-product. It is probably a matter of temperament, and for anything I know it may be glandular. But it is not something that can be demanded from life, and if you are not happy you had better stop worrying about it and see what treasures you can pluck from your own brand of unhappiness."
Robertson Davies

"Worry a little bit every day and in a lifetime you will lose a couple of years. If something is wrong, fix it if you can. But train yourself not to worry. Worry never fixes anything."
Mary Hemingway
