The 50-50-90 rule: Anytime you have a 50-50 chance of getting something right, there's a 90% probability you'll get it wrong.
Sentiment: NEGATIVE
If there is a 50-50 chance that something can go wrong, then 9 times out of ten it will.
Sometimes the probabilities are very close to certainties, but they're never really certainties.
I've found the 90-10 rule to be pretty true: 90 percent of what I come up with and write down is kinda 'eh,' and then somehow, someway, 10 percent of it happens to work out really great in my act.
Chance happens to all, but to turn chance to account is the gift of few.
If a speculator is correct half of the time, he is hitting a good average. Even being right 3 or 4 times out of 10 should yield a person a fortune if he has the sense to cut his losses quickly on the ventures where he is wrong.
It doesn't matter what odds are on paper or what's happened before. It matters what happens that moment.
The laws of probability, so true in general, so fallacious in particular.
When something is important enough, you do it even if the odds are not in your favor.
This 90/10 rule holds true in almost anything financial. Take the game of golf, for example. Ten percent of the professional golfers make 90 percent of the money.
If you put out 150 percent, then you can always expect 100 percent back. That's what I was always told as a kid, and It's worked for me so far!
