“There’s no place like home.”

What does it mean?

Your own home is the most comfortable place to be.

Where does it come from?

Found in J.K. Paulding’s The Backwoodsman (1818), which reads,

Whate’er may happen, wheresoe’er we roam, However homely, still there’s naught like home,”

though an earlier quotation appears in Piomingo’s The Savage (1810).
