Entitlement is just the grossest kind of human behavior.

It's not what happens to us, but our response to what happens to us that hurts us.

The crime of suicide lies rather in its disregard for the feelings of those whom we leave behind.

Human behavior is incredibly pliable, plastic.

My theory was that what I had to do was make a study of human behavior.

If we return to the roots of planning we see at its heart a desire to understand human behaviour and provide a robust model for influencing it. Rather than dismantling strategy into endless experimentation, we need a new way of understanding the world, a modern philosophy.
