‘I Used to Work Nights’: Past Habits That No Longer Exist

CEFR B1  ·  5 min

From my experience:

I used to start every shift with a double espresso I pulled myself. I would stand at the empty bar at 5 PM, before any guests arrived, and just breathe. I do not do that anymore — different country, different life. That gap between then and now is exactly what ‘used to’ is for.

Today's focus: Used to + infinitive (past habits/states); would + infinitive (past habits only)

Used to describes habits AND states in the past that have now changed:

  • ‘I used to smoke.’ (habit, now stopped)
  • ‘He used to be very shy.’ (state, now changed)

Would describes repeated past actions only — NOT states:

  • ‘She would check the reservations twice every night.’ ✓
  • ‘I would live there.’ ✗ (state — cannot use ‘would’ here)

Simple rule: If you can replace it with ‘used to’, ‘would’ probably works. But ‘used to’ can go where ‘would’ cannot.

Examples in context

I used to work sixty-hour weeks in Sydney. Now I work half that. (past habit → changed)
She would always check the reservations list twice before service. (repeated past action)
He used to be a barista before he became head sommelier. (past state — ‘would be’ ✗)

▶ Which is correct? ‘I ___ live in Paris, but now I’m in Réunion.’ (used to / would)
✓ Answer: used to — ‘live’ is a state, not an action. ‘Would’ cannot be used for states.
States: live, be, know, believe, have, love. These only work with ‘used to’, not ‘would’.
▶ Both correct or one wrong? ‘I used to drink coffee every morning.’ / ‘I would drink coffee every morning.’
✓ Answer: Both are correct! ‘Drink’ is a repeated action, so both ‘used to’ and ‘would’ work here.
For actions, both forms work. Only ‘used to’ works for states.
▶ What is the question form of ‘used to’?
✓ Answer: ‘Did you use to…?’ (not ‘did you used to’) — ‘use’ without the ‘d’.
Question: ‘Did you use to live in Australia?’ Negative: ‘I didn’t use to drink tea.’
⚡ 5-second rule:

For states (live, be, have, know): only used to. For repeated actions: both used to and would work. When unsure, use ‘used to’ — it’s always safe.
