I'd just like to point out that this will be awful in Irish - there is no one word for the verbs of these words and they are usually expressed with noun phrases
(except for "live", but in Irish this just has the meaning of "to survive" rather than the "enjoy life" meaning in English - So I've translated it as "have a great life")
