Obama: 'You Can't Change Washington from the Inside'

President Obama, ultimate Washington insider after nearly four years in the White House and part of a Senate term before that, says that this is the most important lesson he has learned in the presidency.

Here are some other lessons he could have learned:

Balancing a budget.

Having a budget in the first place.

America is a nation of laws, not of men.

The American flag actually means something very important to a majority of Americans.

Free speech isn’t optional.

Defending free speech isn’t optional for an American president.

Defending free speech used to be routine for American presidents.

Feel free to add your own lessons that Barack Obama should have learned either before or during the presidency in the comments.
