Does Luck exist?

Do you think Luck Exist?
 I never really think Luck exist. I know that everyone thinks that Luck is real, but actually what everyone does in their life. Its Just the Opportunities that people take. I mean if you don't take advantage of what comes in your way then how can you improve. Luck might just be in that one Single Opportunities, you know you can'y always be afraid of taking the one extra step. A lot of people think that Luck is always easy to get, but how I said its all in the Opportunities. Whatever comes in your way, just take it don't be afraid JUST TAKE IT AND YOU MIGHT BE SURPRISED ON WHAT THE OUTCOME CAN BE! :D
