I chose that you can think positive, but you can't force luck. I also agree with four4me because each day we have some luck that comes our way. I feel lucky just to have a roof over my head. On the other hand, I'm not sure the term is "luck" at all.
Regarding a "near miss" - last week there was a bad accident ahead of me. Was I lucky because I was a few minutes behind? Sure, I was. Does that means the driver ahead of me was very unlucky? Was he just in the wrong place at the wrong time when the truck next to him hydroplaned and spun into his car? I have a friend whose husband was shot to death in a convenience store. Last month I was shocked when I read in the paper that a former co-worker & friend drowned in a freak boating accident. So are all these people very, very unlucky because I'm still here? My next door neighbor was diagnosed with cancer 4 years ago and still smokes his brains out, but he hasn't kicked the bucket yet (which is a mystery to me) so maybe he's much luckier than my aunt who died from lung cancer in February only months after being diagnosed. By the way, she never smoked a day in her life.
Yesterday I turned on the news and a plane had just landed on top of a home because it was trying to make an emergency landing and missed the airport. A family is in critical condition. Could they have gone back in time to prevent this horrible quirk of fate? (anyone ever see the movie Donnie Darko?) Did their thoughts cause the pilot to land short of the runway?
People talk about past lives and "Karma" but does this mean if, in another life, you were cruel and thoughtless you are now doomed to pay for the sins of a former being? Are the people who win the big jackpots descendants of saints and do-gooders?
I guess my feeling about luck is that our attitudes can definitely have a strong influence on what happens in our lives, but all we can do is smile, pray & put our best foot forward, hoping we don't get struck by lightning or get hit in the head by a falling meteorite.
