The secret of being miserable is to have leisure to bother about whether you are happy or not. The cure for it is occupation, because occupation means pre-occupation; and the pre-occupied person is neither happy nor unhappy, but simply alive and active. That is why it is necessary to happiness that one should be tired.
George Bernard ShawRemember that you are a human being with a soul and the divine gift of articulate speech: that your native language is the language of Shakespeare and Milton and The Bible; and don't sit there crooning like a bilious pigeon.
George Bernard Shaw
