Pay attention to the prompt. Each school may be a bit different but they are asking about knowledge, skills and abilities, including psychological strengths, that you bring to the table. Your observation that "things" can be gone in a minute is not really relevant but your flexibility, resourcefulness, and willingness to help neighbors as part of a team all while living in primitive conditions is good material that you should be able to work with in answering specific prompts.
As an aside, if you are a non-native English speaker, please have a trustworthy friend who is a native speaker (ideally an English major or a social science major) take a look at your secondary essays for grammatical correctness. There are a few word choices in your post that are less than ideal.
