Speaking, especially Part 2. I've posted about running out of things to add. Explaining one small moment sounds doable, just not sure what to put in the notes.
Planning for part 2 is mostly the "words" that help you remember a whole idea.
If the question is about "the moment when you felt so proud of yourself", try to write down things like the following:
1. Last year in school
2. The final exam
3. Entry to the university
4. Getting the first place in the town.
Such notes will help you more.
