A bus stop at ten past six in February is a fair test. Dark, cold, nobody watching, and people stand there anyway because something depends on them.
Energy on a morning like that isn't a feeling you wake up holding. It gets generated by moving. The first fifteen minutes are borrowed against, and they're usually repaid by nine.
Courage that early is unglamorous. It's just going. Facing the day is mostly a decision made before the day has given you any reason for it.
