Good luck! / Do your best!
- Word for word
- “Persevere.”
- Politeness: Casual
- Plain form. Fine with family, close friends and people younger than you. Rude to a stranger or a boss.
- When you would say it
- Cheering someone about to take a test, race or interview.
- Worth knowing
- Do not say it to someone already exhausted; it adds pressure.
