Your code is as good as your team

Remember, the upper bound to your code quality is the quality of your team. You cannot make your code better unless you make your team better.

Understanding double dispatch is great for you, but if your team doesn't understand it, it will soon disappear. In order to make your code better, you must interact with your peers.

Interacting with your peers requires two things: 1) You must show people stuff you have learned. 2) You must listen to what others have learned. These discussions will make you better.
