Occassionally? ...about 100 lightning bolts strike the Earth's surface every second. That's about 8 million per day or 3 billion each year. That makes it lucky we're not hit, rather than unlucky when we are imo.
But I'm not a believer in "luck" actually, either good or bad, only probablities. If you believe in 'luck' then the next step is believing in 'fate' and at that point you might as well give up on the statistics and buy yourself a rabbit's foot. The problem is that it's a word thats so pervasive in our language and culture, just try getting through a day without using the word, it's difficult.
webcash, what was the probability that your strategy would fail 9 consecutive times? A couple of years ago we had a run of I think 29 losing favourites on the horses, these things happen. Lots of people stop using otherwise winning strategies because they have a bad start, there's even a YT vid by Peter on the subject. What you need to do before embarking on any strategy is to understand the liklihood of these events occuring, and then set your parameters for failure or success based on probabilities rather than guessing. You might then decide that when you hit a situation that has a liklihood of say 1 or ½% then it's time to move on.
