"I did then what I knew how to do. Now that I know better, I do better." -Maya Angelou
What if someone met you on your worst day? A day in which you may not have acted as your best self. A day in which you look back, and you're not proud. A day in which those things you were dealing with personally were projected on someone else.
What would the perception be of you?
What would that person tell others about you?
Would you want that to be the impression forever burned into his or her mind?
For interns meeting new people, residents returning to locations you've been to before, and attendings who have views of colleagues or consultants that were shaped years ago, remember that people deserve second chances. Consider approaching those you may have a negative view of with a clean slate.
Give them a chance to be their best selves with you.
