Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%.

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.

Everyone by now presumably knows about the danger of premature optimization. I think we should be just as worried about premature design - designing too early what a program should do.

Paul Graham

What is evil? Killing is evil, lying is evil, slandering is evil, abuse is evil, gossip is evil, envy is evil, hatred is evil, to cling to false doctrine is evil; all these things are evil. And what is the root of evil? Desire is the root of evil, illusion is the root of evil.

Gautama Buddha

There are those who say maybe I should forget about football. Maybe I should forget about breathing.

Gerard Houllier

One talks much more about the evil than about the good. That is a paradox. We should only talk about the good to lighten up our existence. Chase anxiousness/fear away for a moment before it sneaks back in again to our life.

Odd Nerdrum

These days, there are a great many books about childhood trauma and its effects, but at the time all the experts agreed that one should forget about it as quickly as possible and pick up where you left off.

Peter Straub

I'm like, "Let me marry a feminist, let's do this thing." It's about time men should show up and say, "Yes, she should have access to whatever she needs."

Sophia Bush

It should be about this team, and it should be about these guys. It should be about our relationship. It shouldn't be about records.

Ezekiel Elliott

Say not "a small event!" Why "small"? Costs it more pain that this ye call A "great event" should come to pass From that? Untwine me from the mass Of deeds which make up life, one deed Power shall fall short in or exceed!

Robert Browning

Be ruthless in one important area: Yourself. Be ruthless about your commitment to Christ. Be ruthless about your intellectual growth. Be ruthless about finishing well. One of the biggest areas we should be ruthless about is our time. How much time do you spend complaining about your problems to people who can't help you solve them? How much time do you talk when you should be doing? When it comes to others, be gracious. But when it comes to you and your time, be ruthless.

Phil Cooke

Idleness, we are accustomed to say, is the root of all evil. To prevent this evil, work is recommended.... Idleness as such is by no means a root of evil; on the contrary, it is truly a divine life, if one is not bored.

Soren Kierkegaard

When I think about life on Earth, there should not be a species like us. And if there was, we should be out in the jungle killing each other in small groups. That's what you should expect.

Jonathan Haidt

You should see what our Founding Fathers used to say to each other and in the early part of our nation. But what they were able to do, especially in Philadelphia in 1787, four months, they argued about what a House should be, what a Senate should be, the power of the president, the Congress, the Supreme Court. And they had to deal with slavery.

Colin Powell
