I believe that it is, Das. It is a conscious decision. You think of all that you would wish you had done if you died without that chance, and you do your best to go to sleep at night with a clear conscience.
To me, it means not leaving undone what I can do, and not doing what is harmful. Making the best of each day. Living one day at a time. Letting someone know that they are loved. They might be gone tomorrow, and we could regret our silence for the rest of our lives,- so I guess it also means living each day as if it might be the last your loved ones have too.
I had a friend who died before I was ready to 'make up' after a quarrel. How I wished I'd swallowed my pride and phoned her! I will never make that mistake again. Pride is cold comfort.
I have had a lot of opportunity to think about my last day, because in 2002 I almost had it! Funny thing, but when you are close to death, (for me anyway) suddenly everything comes into focus, and you see what is really important in life. The mind seems to glimpse a new reality.
So that is why I say: "live each day as if it were your last" - that way, you live in reality.
Patience,
