I think "be your best self" is far more uplifting and positive than the ambiguous "be yourself". The latter leaves open that it is OK to succumb to any negative or bad thoughts, impulses or actions, instead of rejecting or controlling them. Perhaps we should just aspire to smile, don't judge others, do what is good and right, say only good things of others, and don't remain silent or inactive in the face of injustice or cruelty. Or is it OK to not do this if it is at odds with just "be yourself"?
