Lucky break
A piece of good luck that ends in success.
Wish someone luck!
To hope someone is successful.
Thank my lucky stars
Feel grateful for someone's good fortune
Tough luck
Bad luck, sadly
String of good luck
Serie of fortunate events
Luck of the draw
The result of chance and something that you cannot control
To be in luck
To be fortunate
Lucky streak
A serie of wins in gambling
Don't push your luck
To try too hard to get a particular result and risk losing what you have
