"Stop and smell the roses" is an idiom that means to take time out your one's busy life to enjoy the beautiful things in life. "You only live once" or its acronym "YOLO" were commonly used phrase on the internet a few years ago. It means that you should take risks and "live life to the fullest" because you only have one life and it is very short and you don't know when your life will end. "Carpe diem" is a Latin phrase by the Roman poet Horace. It translates as "seize the day". It is widely understood by English speakers to mean " to make the most of the present, and to not worry about the future".

So, tonight, you are holding a party, and, you are telling everybody that they only live once, so, they must enjoy themselves like there is no tomorrow. Because, if there is a tomorrow, there is no need to enjoy like there is no tomorrow, they can leave some of the enjoyment for tomorrow. However, what you are telling them is that they must enjoy themselves as much as they can, they must live for today because tomorrow never comes. What you are calling tomorrow today will be called 'today' tomorrow. So, you may say: You only live once, so, enjoy like there is no tomorrow. or You only live once, so, make merry as never before. or You only live once, live for today, because, tomorrow never comes

All three phrases have one meaning in the end; focusing all your energy and thoughts into the present and not worrying about the past or the future. They're said to wash away the worries and not dwell on things you can't control like the past and future. The moment is right between your hands, seize it! Usually it is said to friends when you are trying to encourage them. Hope this helps!

Both of these answers explain to someone that you treasure every moment and don't want to waste any time. "Be in the moment" - This is a phrase that you can use in many different situations. For example if you are at a music concert and people are filming with their smartphones, that could annoy you and you could say this phrase, because they are not in the moment, instead they are worrying about filming something. "Live for the now" - This literally means live in the present here and now. Do not worry about the past or the future.
