Just remember the English Syllabus clearly tells students to explore & understand the meaning of "Journeys" on their own.
Originality will give you good marks.
Hm...how come you need to create a journal? Is that an assessment task or as a pre-planned extended response for your Section 3, Paper 1 English (Advanced/Standard)?
I find that making up events i.e. in journals (if that's allowed by your teacher) scores you much better marks than saying something that's found in every band 3-4 response like: "Well I went to School today, and god it was boring...I saw a bird fly by...reminding me of the freedom an animal has...etc"
=) A good hint is for you to read up on the English Syllabus for AOS. Though avoid Journal Entries as much as possible unless your teacher explicitly tells you to write one.
