A Quote by Nikola Tesla

Edison was by far the most successful and, probably, the last exponent of the purely empirical method of investigation. Everything he achieved was the result of persistent trials and experiments often performed at random but always attesting extraordinary vigor and resource. Starting from a few known elements, he would make their combinations and permutations, tabulate them and run through the whole list, completing test after test with incredible rapidity until he obtained a clue. His mind was dominated by one idea, to leave no stone unturned, to exhaust every possibility.
"Hope to the last!" said Newman, clapping him on the back. "Always hope; that's dear boy. Never leave off hoping; it don't answer. Do you mind me, Nick? it don't answer. Don't leave a stone unturned. It's always something, to know you've done the most you could. But, don't leave off hoping, or it's of no use doing anything. Hope, hope, to the last!"
If we pursue this way, if we are decent, industrious, and honest, if we so loyally and truly fulfill our duty, then it is my conviction that in the future as in the past the Lord God will always help us. In the long run He never leaves decent folk in the lurch. Often He may test them, He may send trials upon them, but in the long run He always lets His sun shine upon them once more and at the end He gives them His blessing.
Every discoverer of a new truth, or inventor of the method which evolves it, makes a dozen, perhaps fifty, useless combinations, experiments, or trials for one successful one. In the realm of electricity or of mechanics there is no objection to this. But when such rejected failures involve a torture of animals, sometimes fearful in its character, there is a distinct objection to it.
In Paris, the doctors had struggled to make sense of my symptoms - anemia, fatigue and persistent infections. They ran test after test - I was even hospitalized for a week - but the results were inconclusive.
Lincoln had no such person that he could talk with. Often, as a result, he debated with himself, and he would draw up a kind of list of the pros and cons of an argument, and carefully figure them out, and he might test them in public.
God never promised that we wouldn’t have challenges. In fact, He said just the opposite. His word says, ‘Be truly glad!...these trials are only to test your faith, to see whether or not it is strong and pure…’ so if your faith remains strong after being tried in the test tube of fiery trials, it will bring you much praise and glory and honor on the day of His return.
When Edison first started out with his "crazy" idea for the light bulb, skeptics were unmoved. They called Thomas Edison a con man and taunted him to prove his bulb could really work. Despite the naysayers, Edison pushed on, demonstrating the importance of sticking with his "crazy" idea which would go on to turn him into one of the world's most well-known entrepreneurs. The key here is to fan the foolish fire no matter what!
I don't like the idea of a book being a test or being used for a test. The way - in my opinion - to make good readers is to let kids choose their own books and not test them.
I'm proud of my driver test. So many people were waiting for me to test and fail, so they could say that women would never be able to race in F1. I always view my time in F1 as before and after the test. Beforehand, I could sense everybody asking, 'What's she doing in the F1 paddock? Is she good enough?' After my test, that attitude changed.
Continue your quest by taking the test. Yes, but what test? What test was I supposed to take? The Kobayashi Maru? The Pepsi Challenge? Could the clue have been any more vague?
Australianism' means single-minded determination to win - to win within the laws but, if necessary, to the last limit within them. It means where the 'impossible' is within the realm of what the human body can do, there are Australians who believe that they can do it - and who have succeeded often enough to make us wonder if anything is impossible to them. It means they have never lost a match - particularly a Test match - until the last run is scored or their last wicket down.
In most cases the favorable price performance will be accompanied by a well-defined improvement in the average earnings, in the dividend, and in the balance-sheet position. Thus in the long run the market test and the ordinary business test of a successful equity commitment tend to be largely identical.
Ayrton was our toughest rival. He would leave no stone unturned to get the utmost out of his car and his team.
I will leave no stone unturned as far as hard work is concerned.
Test knowledge through experience, be prepared to make mistakes, and be persistent about it.
These fiery trials are designed to make you stronger, but they have the potential to diminish or even destroy your trust in the Son of God and to weaken your resolve to keep your promises to Him. These trials are often camouflaged, making them difficult to identify. They take root in our weaknesses, our vulnerabilities, our sensitivities, or in those things that matter most to us. A real but manageable test for one can be a fiery trial for another.
