"to adjust your behavior" - Best way to tackle this Supplemental Essay?

So, I am quite stuck on one of my supplemental essay. I have no idea which topic I should focus on. Any help would be appreciated. Here is the question and I am applying for pharm school.

"Have you ever been in a situation where you thought you needed to adjust your behavior? How did you know and what did you do?"

Thanks!

From my personal experience, I would assume that if you are applying to pharmacy school, they are looking for a diligent and careful worker. Perhaps write a personal story where you had to adjust your behavior based on the people or events around you. In your personal story talk about your decision, and based on what was around you, talk about how it made you grow as an individual. I hope my ideas sparked something. Good luck! I'm sure you'll do great!

You could write about a time where you might have been interviewed for a job, how did you adjust your behavior to what the employers wanted? Example: being professional

Well... think about your goal. In order to make the reader favor you over other applicants, the trick is to show that you have a well-developed plan with many goals you want to achieve. You should show that you have a meaningful vision for the future.

So, how can this essay be used to show that? You have to be creative.

hint: You might modify your behavior because you realize you are not acting like the kind of person you envision yourself to be...
