U.c. Application Prompt Advice (intented major)

The deadline is approaching and I still have not figured out what to say for both prompts for the U.C.'s application. The first one asks:

Tell us about a personal quality, talent, accomplishment, contribution or experience that is important to you. What about this quality or accomplishment makes you proud and how does it relate to the person you are?

How can I figure out what to talk about with this prompt?

For this prompt, I am going to talk about my intended major (sociology) and how my interest developed in it.

What is your intended major? Discuss how your interest in the subject developed and describe any experience you have had in the field - such as volunteer work, internships and employment, participation in student organizations and activities - and what you have gained from your involvement.

Okay, so you have the prompts. Now, write something that addresses them. I have no idea what personal qualities, talents, accomplishments, or experiences you possess or have had that you could talk about. For all I know, you have no positive personal qualities, have never accomplished anything, and have only had dull, mundane experiences. Your job is to convince the reader of your essay that this is not actually true. So, decide what positive quality you have that you want the reader to know about, and then show, rather than tell, the reader that you have this by describing a relevant experience you have had.
