Luck

There are many definitions to discribe luck. I will write some of them:
1.Luck (also called fortuity) is a chance happening, or that which happens beyond a person's control. Luck can be good or bad (as in; Good fortune or misfortune).
2.fortune: your overall circumstances or condition in life (including everything that happens to you); "whatever my fortune may be"; "deserved a ...
3.an unknown and unpredictable phenomenon that causes an event to result one way rather than another; "bad luck caused his downfall"; "we ran into each other by pure chance"
Everyone choses the definition about luck for itself.
I think that luck is something good or bad that happens to person that doesn't depend on people. Something mystic that cannot be explain.
I like when people say for me "Good luck", then I feel more relaxed and confident.
All in all, luck is very useful for us, so I want to say everyone "GOOD LUCK"!
