So where's Winston Churchill when you need some rousing oratory on why we have to fight this monster? Ultimately perhaps it's more Hillary who answers the question with the whimsical aside, "because it's there".

We certainly come to appreciate the little things. I spent most of my life living in the future. I thought I was happy enough but my life was slipping away because I didn't see the present and couldn't appreciate it.

It might not be much of a life now but I appreciate it more.
