Almost perfect: I will put within "quotes" what you're missing -Live every moment of your life such that"," even if you die at this moment"," you wont regret the life you have lived thus far. Thank you :-) It's a beautiful form of words.The grammer is fine. Just remember your commas! ^_^

Don't use "even" if you have used "such that", and instead of using "thus" use "so" to make the statement clearer. And use commas to have pauses in sentences. Instead of having this sentence: "Live every moment of your life such that even if you die at this moment you wont regret the life you have lived thus far." You will have: "Live every moment of your life such that, if you die at this moment you wont regret the life you have lived so far."

It depends on if it is a quote. If it is a quote of someone, then you would leave it in its incorrect original form but inside quotation marks.

Yeah..Elena.its hard indeed..may be we should add a 'Try to' at the beginning of this sentence :-)

It's perfectly correct.
