life is good

My grandmother told me this morning:
 It doesn't matter how many years you live
 It doesn't matter how many years you die, that's what matters
 For example, you miss someone, miss something
 If it stays, you will never understand
 What was life...

I'm here right when I need to be and I'm moving forward because I don't have to stop in time

This means we become so accustomed to the good and the good people in our lives that their presence fades into the background, simply because they've always been there.
