(1) family/childhood, (2) heritage/culture/roots, (3) accomplishments/achievements, and (4) legacy left behind? And what kind of container would you put it all in?

My timecapsule

If I had to pick four things that are important to me to put in my time capsule I would put...
1. The last remaining piece of my blue blanky that I carried everywhere when I was little.
2. My silver cross necklace.
3. My silver medal from the alumni regatta I raced in a few years ago because I won it with my dad. 
4. Every single book of songs that I have written.
Everything would be kept in a mason jar with my mom's handwriting on the lid "apple butter".
