・life has its ups and downs
・life is full of ups and downs

「人生有起有落」可以用英語的 life has its ups and downs 或 life is full of ups and downs 等來表達。

Life has its ups and downs, so even if it's hard right now, I'm sure you'll have fun soon.
（因為人生有起有落，所以即使現在很困難，我相信很快就會再次變得有趣。）

Life is full of ups and downs, but let's do our best together.
（人生有起有落，但是一起加油吧。）
