Knowing that death is certain kind of helps me to live fully, making the most of the time as much as possible.
My life is currently not a ten out of ten certainly. I still have areas I have to improve and expectations I have of myself which I am yet to accomplish but it doesn't bother me. I keep getting there with each passing day.
Hopefully you know a few things you can do to move your life-score closer to ten out of ten. I'm not sure anyone would ever attain it, but moving towards it will certainly make life more enjoyable.
