Bacchylides on worrying too much

A short warning today, from Bacchylides's, Processionals

“There is one border, a single path to happiness for mortals—
When a person is able to keep a heart free of grief
Until the end of life. Whoever keeps a ten thousand
Affairs in their thoughts
Whoever tortures their heart
Night and day over what may come,
Has toil which brings no profit.”

[fr. 11-12]
