Failure is Central to engineering. Every single calculation that an engineer makes is a failure calculation.
Failure is central to engineering. Every single calculation that an engineer makes is a failure calculation. Successful engineering is all about understanding how things break or fail.
I emphasize that virtually every engineering calculation is ultimately a failure calculation, because without a failure criterion against which to measure the calculated result, it is a meaningless number.
Calculation has its advantages, but no one likes naked calculation.
Monetary calculation is not the calculation, and certainly not the measurement, of value. Its basis is the comparison of the more important and the less important. It is an ordering according to rank, an act of grading (Cuhel), and not an act of measuring. It was a mistake to search for a measure of the value of goods. In the last analysis, economic calculation does not rest on the measurement of values, but on their arrangement in an order of rank.
Perfectionist is sometimes the wrong word... It means like you're never satisfied, or you're upset by every single failure - any type of failure. And so for me, I don't look at failure as necessarily a bad thing as long as I'm able to learn from it and take something from it, so that next time I'm in that situation I know how to succeed.
Failure is not a single, cataclysmic event. You don't fail overnight. Instead, failure is a few errors in judgement, repeated every day.
The best calculation is the absence of calculation. Once you have attained a certain level of recognition, others generally figure that when you do something, it's for an intelligent reason. So it's really foolish to plot out your movements too carefully in advance. You're better off acting capriciously.
In a world in which the price of calculation continues to decrease rapidly, but the price of theorem proving continues to hold steady or increase, elementary economics indicates that we ought to spend a larger and larger fraction of our time on calculation.
Failure is an event, something that happens at a specific time on a certain day. If you want to be successful, you have to embrace failure and get back up every single time.
If you are going to have a risk-taking culture, you can't really look at every failure as a failure, you've got to be able to look at the failure as a learning opportunity.
There is failure in every industry; there is failure in every step. It's just that we are working in an industry where everything is just out there; that is why it looks so magnified. But failure is a part of life.
What a shame to be so afraid of failure that you stop living. My wife has a great one-liner about failure: "Never consider yourself a failure-you can always serve as a bad example." She is right. Failure can be a better teacher than success.
Cultivate your desire for success to be greater than the fear of failure; Failure is merely a pitstop between where you stand and success. Failure allows you to learn the fastest; Failure inspires winners and defeats losers.
Morality must guide calculation, and calculation must guide politics.
The Great Depression was not a sign of the failure of monetary policy or a result of the failure of the market system as was widely interpreted. It was instead a consequence of a very serious government failure, in particular a failure in the monetary authorities to do what they'd initially been set up to do.
This idea that failure is not an option: It makes failure invisible, inconceivable and inevitable.
