“To understand how to get to where you are going, you must first know where you are – and it helps to understand how you got to where you are today.  My most exasperating driving experience is hearing my co-piloting wife, gazing at the map, say, ‘You should have turned left three streets back’ – to which I invariable reply, ‘Unless you are piloting a time machine, you cannot should have done anything on planet earth.’  Reality harshly teaches us that we can only proceed from where we are now…” –Michael Rood
