I don't know whether the universe, with its countless galaxies, stars, and planets, has a deeper meaning or not. But at the very least, it is clear that we humans, who live on this earth, face the task of making a happy life for ourselves. Therefore, it is important to discover what will bring about the greatest degree of happiness.

With pleasure I write my name in your Album. Ere long some younger man will be more happy to confer his name upon you. Don't allow it, Mary, until fully assured that he is worthy of the happiness.

A lifetime of happiness! No man alive could bear it: it would be hell on earth.

I have this really high priority on happiness and finding something to be happy about.

The necessary thing for anyone to be happy and contented as long as he lives is working for the ones who will come after him rather than working for himself... One can reach the true delight and happiness in the life only by working for the existence, honor, and happiness of the future generations.

Money is numbers and numbers never end. If it takes money to be happy, your search for happiness will never end.
