I quite like the quote that is in my signature at the moment; from a song called 'In The Aeroplane Over the Sea' by a band called Neutral Milk Hotel.

And our ashes will fly
From the aeroplane over the sea

Let us lay in the sun
And count every beautiful thing we can see'
This is the verse that is particularly striking but the whole song holds the very same meaning. It's about living in the present and learning to just live life to the fullest, there are so many beautiful things around us, we should appreciate them whilst we can and there is no point in worrying about things that we won't take to our grave.
