There's nobody unlucky, everybody has the same chance of winning, unless it's a raffle and somebody buys more tickets than you, you can still win, but it's less likely, it's not really luck.
Luck does not exist. I agree with LivingToDie. Some people who are really smart; they can observe how people think and act, and can use that information to figure out how the future may become.
Statistics; some behaviours or circumstances make that certain people are more "lucky" than some others, but it really only is statistical. Remember: Sh*t Happens.
there are some ways to look at luck. when i think about small things id say im really lucky. but when i look about my problems i am very unlucky because there arent many (if any XD) people with the problems i have. i also noticed that being optimistic helps alot. i am not really a risk taker when there is alot to lose but i usually trust my luck and it turns out im really lucky. this might sound stupid but maybe you should just try and believe in your luck.
last thing: i dont know if luck really exists or not. i dont think someone should count on it too much but sometimes luck and hope are the only things left and believing in your luck really helps.
Luck is as real as leprechauns and SANTA. It is just that people take advantage of their situation through either having experience or pure coincidence.
Luck is nothing but probabilities, some people either increase their chance of getting favorable probabilities or in your perception you see that they get something a lot more than you do. But in reality your equally *lucky* but don't notice it.
There's no such thing as luck what happens is for example on a test you might guess a question and get it right that's because you thought about and took a thoughtful guess. Other times you could be good at something like soccer and you're playing against someone better then you and you beat them that's neither because they weren't playing good or you were playing good. So basiclly luck doesn't really exist.
