You look at a herd of cattle and well they all look the same... but they know. They all have an individual personality and those personalities change from day to day. They can have their grumpy days and their happy days and their serene days. But it's unpredictable. You can't be off in outer space when you're dealing with animals.

One reason we resist making deliberate choices is that choice equals change and most of us feeling the world is unpredictable enough try to minimise the trauma of change in our personal lives.

One of the most predictable things in life is there will be change. You are better off if you can have a say in the change. But you are ignorant or naive if you don't think there will be change whether you want it to or not.

For all of nature's wonder and beauty it is also hostile and unpredictable.

The American people are smart. They've gotten sick of the predictable hyperpartisan talking points and canned anger.
