if I know everything about your external world, I can only predict 10 percent of your long-term happiness. 90 percent of your long-term happiness is predicted not by the external world, but by the way your brain processes the world.
・ハッピーになれるかどうかへの影響度は外の環境：考え方＝1：9
What we found is that only 25 percent of job successes are predicted by I.Q. 75 percent of job successes are predicted by your optimism levels, your social support and your ability to see stress as a challenge instead of as a threat.
・仕事の成功は 知能：ポシティブ思考＝25％：75％
If I work harder, I'll be more successful. And if I'm more successful, then I'll be happier. That undergirds most of our parenting styles, our managing styles, the way that we motivate our behavior.
・働く→成功→幸せ！ は今までの考え方
And the problem is it's scientifically broken and backwards for two reasons. First, every time your brain has a success, you just changed the goalpost of what success looked like. You got good grades, now you have to get better grades, you got into a good school and after you get into a better school, you got a good job, now you have to get a better job, you hit your sales target, we're going to change your sales target. And if happiness is on the opposite side of success, your brain never gets there. What we've done is we've pushed happiness over the cognitive horizon as a society. And that's because we think we have to be successful, then we'll be happier.
・従来考え方には2つ問題があって
1つは成功すればするほど、高みをもとめてしまい また成功しないと幸せを感じれないスパイラルになる
脳はいつまでも幸せを感じられない。
But the real problem is our brains work in the opposite order. If you can raise somebody's level of positivity in the present, then their brain experiences what we now call a happiness advantage, which is your brain at positive performs significantly better than it does at negative, neutral or stressed. Your intelligence rises, your creativity rises, your energy levels rise. In fact, what we've found is that every single business outcome improves. Your brain at positive is 31 percent more productive than your brain at negative, neutral or stressed. You're 37 percent better at sales. Doctors are 19 percent faster, more accurate at coming up with the correct diagnosis when positive instead of negative, neutral or stressed. Which means we can reverse the formula. If we can find a way of becoming positive in the present, then our brains work even more successfully as we're able to work harder, faster and more intelligently.
・脳の本来の働きの順番は ポシティブな考え→効率的に働く
ポシティブに考えるとネガティブな時に比べ31％生産性アップ。
What we need to be able to do is to reverse this formula so we can start to see what our brains are actually capable of. Because dopamine, which floods into your system when you're positive, has two functions. Not only does it make you happier, it turns on all of the learning centers in your brain allowing you to adapt to the world in a different way.
・ポシティブな考え→ドーパミン発生→幸せを感じる＋物事へのアプローチがかわる
We've found that there are ways that you can train your brain to be able to become more positive. In just a two-minute span of time done for 21 days in a row, we can actually rewire your brain, allowing your brain to actually work more optimistically and more successfully. We've done these things in research now in every single company that I've worked with, getting them to write down three new things that they're grateful for for 21 days in a row, three new things each day. And at the end of that, their brain starts to retain a pattern of scanning the world, not for the negative, but for the positive first.
And by doing these activities and by training your brain just like we train our bodies, what we've found is we can reverse the formula for happiness and success, and in doing so, not only create ripples of positivity, but create a real revolution.
