All the days of the afflicted are evil: but he that is of a merry heart hath a continual feast.
– Proverbs 15:15
The word for afflicted means depressed, as in mind or circumstances. The word for evil means bad or painful. The parallelism makes plain the state of the afflicted comes from the state of the heart (Proverbs 15:13; 17:22). The word for merry means good and agreeable. This is reinforced by continual feast, which points to sustained pleasure and delight. The hint here is that even our experiences are affected by our state of mind and outlook (Proverbs 16:22). We might say to the miserable, everything is miserable, and to the happy, everything is happy.
