"When things go wrong and will not come right,

Even if you know what you are doing, things go wrong. Things go wrong because building a multifaceted human organization to compete and win in a dynamic, highly competitive market turns out to be really hard.

The sad truth is that certain types of things can't go backward. Once they start going forward, no matter what you do, they can't go back the way they were. If even one little thing goes awry, then that's how it will stay forever.

When things go wrong, you'll find they usually go on getting worse for some time; but when things once start going right they often go on getting better and better.

If anything can go wrong, fix it! (To hell with Murphy!)

You can’t concentrate on doing anything if you are thinking, “What’s gonna happen if it doesn’t go right?

If something is wrong, fix it if you can. But train yourself not to worry. Worry never fixes anything.

It's worth noting that the assumption that something can't happen has the potential to make it happen, since people who believe it can't happen will engage in risky behaviour, and thus alter the environment.

Engineers speak half–jokingly about Murphy's Law: " If anything can go wrong, it will." But complexity stands under a second law as well. Let me call it Drucker's law: "If one thing goes wrong, everything else will, and at the same time."

The only impossible thing is something to be impossible.

There is fear of failure here. People keep saying what if this goes wrong, what if that doesn’t work. Every time I want to do something, there is this fear that it may go wrong. It comes up each time.

For this to work, a million things have to go right. For it to fall apart, just one of them has to go wrong.

One cannot say that it will never happen again, or that it cannot happen.

إنّ مجرد كون العقل البشري لا يستطيع تخيل حدوث شيء.. لا يعني أن ذلك لن يحدث.
