Where do you see yourself 5 years down the line?
This is part of that autobiography, isn't it?
With these essays, you will be giving a full picture of your envisioned future. For example, if you know what you want to be doing in 5 years, it is because you know what kind of life you want to lead and what kind of legacy you want to leave. Also, you know what people influence you in that direction, right? Whom do you admire? Use the essay about a trip with 2 people as an opportunity to show them what kind of person inspires you. What are you passionate about?
The event you think is wrong shows your moral development, the challenge you describe shows your experience and areas of interest. These essays are a great way for the reader to know you, and if you know yourself you can respond to each part.
I look forward to seeing what you write! If you are not sure how to respond to part of this, ask your inner self, the self that is calling the shots and trying to get this incorrigible person to do the necessary work each day. :-)
