2. Rules
All the Doctors have had one rule: Dont wander off. It wasnt until Eleven, though, that we started getting some more. We have rules such as Never knowingly be serious, Always waste time when you dont have any, and Never Run When Youre Scared to name a few. Ive always loved the Doctor's rules because theyre really great life lessons, if you think about it. I also like the fact that the Doctor has more than just dont wander off because it gives us a glimpse into his mind, and how he thinks. All of these rules come from a pure heart and a silly mind, and that's exactly what Eleven is. He cares for people, and he knows that time is sacred and people should spend it wisely. I dont believe that he spouts out these rules to be annoying, I think he has them because hes lived for so long. Of course, there is also "Rule 1: The Doctor Lies", this rule is the most prominent because he lies so that the people around him are safe. He lies so that people around him aren't scared. He lies to keep his own worries tucked away. This is the most important rule the Doctor has. There is also the fact that in A Good Man Goes to War, he mentions that he has a lot of rules because hes a good man. However, these rules are probably more of what weve seen in every Doctor, giving people a chance, what he's learned from the Time War, etc.
