Did You Believe in Luck??

Hi, I am Arveno from Surabaya city. In this content i want to asking you guys about my question in my life that is about LUCK. Did you guys believe about Luck??
Or did you guys ever felt and thinking about luck in your life??
I actually believe God instead this Luck thing. But, sometimes i questioning about this.
For example because i am a detail person. Every rain season, I always memorized when the rain comes. And i dont know this is coincidental or its my bad luck i still dont know. But, in the past 5 months. Almost everytime when i need to go or whenever I am not at home. It always raining. FYI, i am mostly spending my time at home or even inside the building not outside. Its weird right?
But its really happened to me in this past 5 months.

Like today for example. This is real happened. One day is 24 hour but yet when i need to take my son and my wife to school in the morning. The rain started. At first i though it just happens. But, whats weird is after i got back at home ( I am at home all day long) the rain stopped and the cloud gone. Its like univers playing with me. Then in the evening when i need to pick up my wife and my son, the rain started to fall again. Because of this incident, now i think it is not accidentally. It is like well arranged. So, still I wont believe in Luck but if this happening everytime. I think I definately will think that Luck is real and it needed in Life. And the bad side is we cannot pick or choose how much and how big our luck. Or maybe because of this many people in the world always said that this world will never be fair. Because of luck that well arranged for some people that getting more than other people. What do you guys think about this Luck??
