Think of home.
That feeling you just had is home, and it lives inside your mind, engraved on your soul. Think about what this means: that home is readily available to you, regardless of where you are.
Move to a new country, where you don’t know anybody. At some point, you will feel lonely and long for your safe place.
The taste of the hot chocolate your mom makes, the first chords of your favorite song, the pages of your favorite book. They all take you home, whenever you need. Just make that hot chocolate, play that song, read that book, and you will find the comfort of belonging.
Home is not where the heart is, because the heart is wherever you put it. Home is where you make it.
