What it means: Two related uses:

1. Busy and active: Always doing things, constantly occupied.
"She's always on the go — never stops."
"I've been on the go since 7am."

2. While moving or travelling: Doing something while in transit, not stationary.
"Breakfast on the go." (eating while commuting)

What it implies in meaning 1: Energetic busyness — the person doesn't sit still. Can be admiring ("she's incredibly on the go") or exhausted ("I've been on the go all day and I'm shattered").

• "Always busy" — meaning 1
