In the article "Cracked Pots" it relates to being yourself when it says: "The bearer said to the pot, “Did you not notice that there were flowers only on your side of the path, and not on the other pot’s side?

This shows how you can be yourself, even when you make bad decisions being yourself you shouldn't beat yourself up over it.
Even though everyone else is sad in the world doesn't mean that you have to be sad as well. This shows that being yourself can be a great thing even in the hardest times.
This shows that instead of just being yourself, you should be yourself and be proud of it.
In the short story Angus Bethune a major theme is be yourself.
