Consider creating a travel scrapbook with a mix of physical and digital elements. Collect tickets, postcards, and local memorabilia, then pair them with QR codes linking to videos or voice recordings of your experiences. This hybrid approach preserves tangible memories while incorporating multimedia.
Alternatively, start a personal blog or vlog with a private setting, allowing you to reflect deeply without social media pressures. Use platforms like WordPress or Notion to organize entries by themes—cultural insights, language progress, or personal growth—creating a structured narrative of your journey.
