Thomas Fuller (baptised 19 June 1608 – 16 August 1661) was an English churchman and historian. He is now remembered for his writings, particularly his Worthies of England, published in 1662 after his death. He was a prolific author, and one of the first English writers able to live by his pen (and his many patrons).

The belief that unhappiness is selfless and happiness is selfish is misguided. It's more selfless to act happy. It takes energy, generosity, and discipline to be unfailingly lighthearted, yet everyone takes the happy person for granted. No one is careful of his feelings or tries to keep his spirits high. He seems self-sufficient; he becomes a cushion for others. And because happiness seems unforced, that person usually gets no credit.
