Focus on getting product market fit.
專心把產(chǎn)品搞好
Because in the end, as Sam said in the beginning of this course, idea, product, team, execution.
因為歸根結(jié)底，如Sam在本課開始提到的創(chuàng)意，產(chǎn)品，團(tuán)隊，執(zhí)行
If you don't have a great product, there's no point executing well on growing it.
如果沒有好產(chǎn)品執(zhí)行增長策略也沒什么意義
Because it won't grow.
因為，增長不了
Number one problem I've seen inside Facebook for new products, number one problem I've seen for startups I ever devised has been,
我在Facebook內(nèi)部看到的我在合作過的創(chuàng)業(yè)公司中看到的
they don't actually have product market fit when they think they do.
最主要的問題是，沒有好產(chǎn)品，但是他們認(rèn)為有
So the next obvious question that people ask over and over and over again is okay,
下一個顯然的問題人們反復(fù)問的一個問題是
so what does good retention look like?
好的用戶留存率什么樣？
Sure I can have five percent retention but
你可能說：我們公司只有5%的留存率
I'm guessing that Facebook had better than that, so that's not gonna be a successful business.
（Facebook的留存率要好一些）所以我們是失敗的
And I get really pissed off when people ask me that question.
當(dāng)人們問我好的用戶留存率什么樣時，我會生氣
Because I think you can figure it out.
因為可以自己算啊
And I love this story, and this is like my one gratuitous story that I love that I'm throwing in here, so the rest of it may not be as gratuitous.
我喜歡這個故事，可能有點(diǎn)像“閑篇子”我在這里給大家講講這個故事的后半部分比較有用
But this is a picture that was published in
這幅三位一體核試驗圖片發(fā)布于
Life magazine in 1950 of one of the Trinity nuclear bomb tests.
1950年的Life雜志上
And there's a guy, Geoffrey Taylor, who's heard of Geoffrey Taylor.
有個叫Geoffrey Taylor的人，有同學(xué)知道Geoffrey Taylor嗎？
Awesome. Yes. Someone's heard of him.
很棒，有人知道
Geoffrey Taylor was a British physicist, who ended up actually winning the Nobel Prize.
Geoffrey Taylor是一名英國物理學(xué)家他后來獲得了諾貝爾獎
And he was able to figure out from looking at this picture, what the power of the atomic bomb was, the U.S. atomic bomb.
他能根據(jù)這幅圖片求出原子彈的威力這是美國的一顆原子彈
And Russian's were publishing similar pictures, just using dimensional reasoning.

And dimensional reasoning is I think, one of the best skills that I learned during my time studying physics back in the U.K..
這種技巧是我在英國讀物理時學(xué)到的最好的方法
And what dimensional reasoning is, is you look at the dimensions that are involved in a problem.
其原理就是看一下問題中涉及的量綱
So, you wanna figure out energy?
如果想計算出能量
Newtons, meters, newtons as kilograms, meters, second to the minus 2, so you've got kilograms, meters squared, seconds to the minus 2,
能量等于牛頓·米牛頓等于千克·米/秒^2所以能量就等于千克·米^2/秒^2
and then you try and figure out how you can get each of those numbers from what data you have.
所以你就要算出其中各個值具體是多少
