Sophie Scholl wrote that the yardstick inside every person is the "most difficult yardstick." What do you think she meant? What standards did she try to hold herself to?

I can't write your essay for you but Sophie essentially means that we all have standards each induvial hold for themselves. We strive to live up to something or someone that we want to be. Most of the time we fall short or are disappointed because we do not measure up to our own expectations.
