I don't think you should have to try to be nice, I think most people are nice. I think being cheerful and nice is just a politeness.

While there is a chance of the world getting through its troubles, I hold that a reasonable man has to behave as though he were sure of it. If at the end your cheerfulness in not justified, at any rate you will have been cheerful.

There is only one way to get ready for immortality, and that is to love this life and live it as bravely and faithfully and cheerfully as we can.

There is no personal charm so great as the charm of a cheerful temperament.

The Middletons and the Windsors might seem at first glance to be worlds apart. Kate certainly shows no sign of adopting the horsey, doggy lifestyle beloved of her grandmother-in-law. But the Queen admires how well Kate has embraced royal life, combining it cheerfully with duty and motherhood.

He who loveth a book will never want a faithful friend, a wholesome counsellor, a cheerful companion, or an effectual comforter.

But I think I can sincerely declare that I cheerfully submit myself to every odious name for conscience' sake; and from my soul I despise all those whose guilt, malice, or folly has made them my foes.
