W. Somerset Maugham said this quote

He was terribly conscious that he only had one life and with seemed to sad to think that he had wasted it. He could never surmount his immeasurable regret. And that's why I tell you that Byring is right. Even though it only lasts five years, even though he ruins his career, even though this marriage ends in disaster, it will have been worth while. He will have been satisfied. He will have fulfilled himself.
