Luck is always unpredictable, it is like the fruit that bears from your hard works, all the efforts and time you spent to achieve your dreams just paid of. I guess luck is something that we must consider as a success, all of the people who lives in this whole wide world believes in that, but we have different luck in life, we share different future, so if someone's get lucky on a certain thing, don't expect that it could also happen to you, you might leave yourself hanging around expecting.
