If you're like us, you are a devotee of The Two Things Theory: “For
every subject, there are only two things you really need to know. Everything
else is the application of those two things, or just not important.”
For
instance, Nicholas Kronos' theory on The Two Things about Creativity:
1. God is in the details.
2. The devil is in the details.
And our own The Two Things about Art Directors:
1. You work for the client.
2. Get over it.
