This is no time for on the job training.

Asked about the greatest lesson he’d learned about the presidency from studying about Abraham Lincoln, Obama said:

“You know, when I think about Abraham Lincoln, what I’m struck by is the fact that he constantly learned on the job. He got better. You know, he wasn’t defensive. He wasn’t arrogant about his tasks. He was very systematic in saying, ‘I’m going to master the job, and I understand it’s going to take some time.’ “
