How do you say live life to the fullest in Hebrew?

There isn't one single perfect translation for "live life to the fullest" in Hebrew, as the nuance depends on what aspect of "fullest" you want to emphasize. However, here are a few options, each with slightly different connotations:

* לחיות את החיים במלואם (l'chiyot et hachayim b'mloam): This is a fairly literal translation, meaning "to live the life in fullness." It's a good general option.

* לחיות חיים מלאים (l'chiyot chayim mal'im): This translates to "to live a full life." It's similar to the previous option but slightly less emphatic.

* לחיות את החיים עד תום (l'chiyot et hachayim ad tom): This translates to "to live life to the end," or "to live life until the end." It emphasizes living until the very last moment, potentially with a sense of urgency.

* ליהנות מכל רגע (li'hanot mikol rega): This translates to "to enjoy every moment." This focuses on the experience and pleasure derived from life.

The best option depends on the context. If you want a general expression, לחיות את החיים במלואם (l'chiyot et hachayim b'mloam) or לחיות חיים מלאים (l'chiyot chayim mal'im) are good choices. If you want to emphasize enjoying each moment, ליהנות מכל רגע (li'hanot mikol rega) is more appropriate.
