I'm always looking for it to happen in my life. But still, I see in dictionaries and from other people. I didn't meet the word in reality.
You don't have to look after it. It comes exactly when you expect it the least. Everytime I was looking for luck, I never found it. Exactly when I didn't expect it, it came and I won! Be sure not to play with more than you can afford. A small mistake and it could go worse than you can imagine.
