This has often been attributed to Sun Tzu and sometimes to Petrarch. It comes most directly from a line spoken by Michael Corleone in The Godfather Part II (1974), written by Mario Puzo and Francis Ford Coppola:
My father taught me many things here. He taught me in this room. He taught me: keep your friends close but your enemies closer.
Niccolò Machiavelli, who is also sometimes credited, wrote on the subject in The Prince:
It is easier for the prince to make friends of those men who were contented under the former government, and are therefore his enemies, than of those who, being discontented with it, were favourable to him and encouraged him to seize it.

Context: Who's to say that young girls who like pop music – short for popular, right? – have worse musical taste than a 30-year-old hipster guy? That's not up to you to say. Music is something that's always changing. There's no goal posts. Young girls like the Beatles. You gonna tell me they're not serious? How can you say young girls don't get it? They're our future. Our future doctors, lawyers, mothers, presidents, they kind of keep the world going. Teenage-girl fans – they don't lie. If they like you, they're there. They don't act 'too cool.' They like you, and they tell you. Which is sick.

Variant: Just keep moving forward and don't give a shit about what anybody thinks. Do what you have to do, for you.

True origin unknown. Finest Hour described it as "not verifiable in any of the 50 million published words by and about him" ( Finest Hour, The Journal of Winston Churchill, Number 145, Winter 2009–10, p. 9 https://www.winstonchurchill.org/images/finesthour/vol.01%20no.145.pdf). A similar quotation: "If you're going through hell, don't stop!" is "plausibly attributed" to Oregon self-help author and counselor Douglas Bloch (1990), according to Quote Investigator.

Thiis was published without credit in The Best Loved Poems of the American People (1936) with the title "Friendship", and since that time has sometimes been misattributed http://www.geonius.com/eliot/quotes.html to Eliot; it is actually an adaptation of lines by Dinah Craik, in A Life for a Life (1859):
Misattributed
Context: Oh, the comfort —
the inexpressible comfort of feeling safe with a person —
having neither to weigh thoughts nor measure words,
but pouring them all right out,
just as they are,
chaff and grain together;
certain that a faithful hand will take and sift them,
keep what is worth keeping,
and then with the breath of kindness blow the rest away.

In an interview with Stone Phillips, Dateline NBC (29 November 1994)

Machiavelli commented on the relative ease of gaining favor from friends and enemies in Chapter 20 of The Prince, quoted above. However, this particular wording comes from a line spoken by Michael Corleone in The Godfather Part II (1974), written by Mario Puzo and Francis Ford Coppola:
My father taught me many things here. He taught me in this room. He taught me: keep your friends close, but your enemies closer.

" An Interview with Jane Goodall https://web.archive.org/web/20100920074838/http://www.idausa.org:80/essays/goodallinterview.html", In Defense of Animals (date unknown)
Context: Researchers find it very necessary to keep blinkers on. They don't want to admit that the animals they are working with have feelings. They don't want to admit that they might have minds and personalities because that would make it quite difficult for them to do what they do; so we find that within the lab communities there is a very strong resistance among the researchers to admitting that animals have minds, personalities and feelings.

As quoted in O₂ : Breathing New Life Into Faith (2008) by Richard Dahlstrom, Ch. 4 : Artisans of Hope: Stepping into God's Kingdom Story, p. 63; this source is disputed as it does not cite an original document for the quote. It is also used in <i> The White Rose </i> (1991) by Lillian Garrett-Groag, a monologue during Sophie's interrogation.
Disputed
Context: The real damage is done by those millions who want to "survive." The honest men who just want to be left in peace. Those who don't want their little lives disturbed by anything bigger than themselves. Those with no sides and no causes. Those who won't take measure of their own strength, for fear of antagonizing their own weakness. Those who don't like to make waves — or enemies. Those for whom freedom, honor, truth, and principles are only literature. Those who live small, mate small, die small. It's the reductionist approach to life: if you keep it small, you'll keep it under control. If you don't make any noise, the bogeyman won't find you. But it's all an illusion, because they die too, those people who roll up their spirits into tiny little balls so as to be safe. Safe?! From what? Life is always on the edge of death; narrow streets lead to the same place as wide avenues, and a little candle burns itself out just like a flaming torch does. I choose my own way to burn.

Context: Looking back, I think he knew that in my innocence I was eager to love everything and please everybody, and he was trying to warn me not to lose my own identity in the process. Time after time he came back to this theme. " The individual has always had to struggle to keep from being overwhelmed by the tribe. To be your own man is a hard business. If you try it, you'll be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself."

"Stopping by Woods on a Snowy Evening" (1923) http://www.poetryfoundation.org/poem/171621
Variant: And miles to go before I sleep.
Context: The woods are lovely, dark and deep.
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

Variant: Are you willing to die for what you believe in? The real courage is in living and suffering for what you believe.

Variant: How we need that security. How we need another soul to cling to, another body to keep us warm. To rest and trust; to give your soul in confidence: I need this. I need someone to pour myself into.

Variant: I don't care if I fall as long as someone else picks up my gun and keeps on shooting.

15 July 1944; Variant translations:
It's really a wonder that I haven't dropped all my ideals, because they seem so absurd and impossible to carry out. Yet I keep them, because in spite of everything I still believe that people are really good at heart.
I keep my ideals, because in spite of everything I still believe that people are really good at heart.
I simply can't build my hopes on a foundation of confusion, misery, and death...and yet...I think...this cruelty will end, and that peace and tranquility will return again.
Source: The Diary of a Young Girl (1942 - 1944)
Context: It's difficult in times like these: ideals, dreams and cherished hopes rise within us, only to be crushed by grim reality. It's a wonder I haven't abandoned all my ideals, they seem so absurd and impractical. Yet I cling to them because I still believe, in spite of everything, that people are truly good at heart. It's utterly impossible for me to build my life on a foundation of chaos, suffering and death. I see the world being slowly transformed into a wilderness, I hear the approaching thunder that, one day, will destroy us too, I feel the suffering of millions. And yet, when I look up at the sky, I somehow feel that everything will change for the better, that this cruelty too shall end, that peace and tranquility will return once more. In the meantime, I must hold on to my ideals. Perhaps the day will come when I'll be able to realize them!
