"When you have eliminated the impossible, whatever remains, however improbable, must be the truth. – Sir Arthur Conan Doyle, stated by Sherlock Holmes"

"To me, this is all about logic. If you start with everything you can think of, and then eliminate those that are impossible, you are well on your way to a solution."

"While some impossibilities might be obvious, sometimes we can be sucked in by an idea that intrigues us, despite being impossible. Other times, it is only in close examination that the impossibility is revealed."

"When things don’t go the way you expected, it’s time to figure out what went wrong, why it did what it did, and how to do it better next time. That starts with eliminating all the impossibilities, and narrowing down the remaining possibilities, in an effort to hunt down the truth."

"How do you figure out what to do after something goes in an unexpected and unpleasant direction? Ask yourself “Why?” and then start eliminating the impossible."

"If all you ever do are things you have already mastered, you will rarely, if ever, make mistakes. But that’s going to be a very boring life to live, won’t it? We make the most mistakes when we try something new. The less like anything else we’ve tried, the more likely we are to make mistakes."

"By learning from each mistake and pursuing the best possible course, we eventually find the sweet spot, and cease making mistakes."

"And what about your pride? Are you graceful and gracious when you make a mistake, or do you get embarrassed and hide from even a minor goof up? If you are afraid to make a mistake, it’s going to be hard to learn, right? You’re going to be afraid to try new things, and you will have a hard time growing, right?"

"What is that belief based on? Why do you believe that making mistakes is a cause for embarrassment, rather than a learning experience? Most of the people you see who do difficult things without mistakes are very good at what they do. They got that way by practice and learning from their mistakes."

"We all make mistakes when trying new things. Yes, we might have a brief run of “beginners luck,” but after that, we’re flailing. Over time we learn and get better. That brings us back to the quote. If we never did anything new, we’d only be doing the things we are good at, and that means few mistakes."

"A person who never made a mistake never tried anything new. – Albert Einstein"
