May your coming year be filled with magic and dreams and good madness. I hope you read some fine books and kiss someone who thinks you're wonderful, and don't forget to make some art -- write or draw or build or sing or live as only you can. And I hope, somewhere in the next year, you surprise yourself.
...I hope you will have a wonderful year, that you'll dream dangerously and outrageously, that you'll make something that didn't exist before you made it, that you will be loved and that you will be liked, and that you will have people to love and to like in return. And, most importantly (because I think there should be more kindness and more wisdom in the world right now), that you will, when you need to be, be wise, and that you will always be kind.
イェール大学の "The Science of Well-Being" という講座を受講しました．復習と備忘録を兼ねて，本記事にまとめます．10週間の講座の要約なので，7000文字程度 (原稿用紙18枚分) の長文になりましたが，とてもおもしろい講座だったので，雑誌かメルマガでも読む感覚でお楽しみ頂ければと思います．どなたかの参考になれば幸いです．
(*3) ネガティブな思考を断ち切るのに，「ストップ」と実際に声を出すのが，意外にも驚くほど効果があるという話は，別の場所でも聞いたことがあります．
また「今あるものに感謝」という点について，教授の "Gratitude is a killer of envy (感謝の気持ちは嫉妬心を撃退してくれる)" という言葉も印象的です．
さらに他人との比較について，前述の通り人は基準値を一切コントロールできずに無意識に受け入れてしまうけど，自分がどんな基準値を受け入れているかを観察することで，健全な情報に触れるようにキュレーションすることはできる，と語っています．
個人的には，なんでも詰め込みがちな自分にとって，「時間的な豊かさを持つ」というポイントが一番響きました．教授と生徒間の Q&A で教授が言っていた，"You just need to take the sharp knife and cut things out (鋭いナイフでバッサリ切らなきゃダメ)" という言葉が，強く印象に残りました．曰く，
このブログで何度か紹介していますが，私は Leo Laporte という，テック系 DJ の大ファンです．今日も，いつものように彼の番組を観ていたところ，とてもおもしろい企画が行われていました．それは，2009年に彼が予測した11年後の未来について，2020年になった今，答え合わせをするというものです．
What if I told you I had a supplement 'S' that would give you,
• Drastically more energy and focus
• Better fat loss,
• Faster muscle gain,
• And it is free.
You'd be all over it right?

身体の変化が感じられるようになるには，週に2回 (1回50分) もワークアウトすれば，まずは十分です．着替えやジムまでの往復を入れても週3時間未満，ジムの利用料は月に1万円未満といったところでしょうか．何が言いたいかというと，他の健康法や嗜好品と，費やすコストと得られる効果を比べた時に，筋トレほど ROI が高いものはないということです．
We all have to think about what kind of world we want to be in, and what kind of world we want to create for our kids.
Don't we want to do the right thing?
Let's do the right thing as best we can.
You don't do it because it's wrong.
Just because that's not the world we want to live in. It's a better world for everybody if people are honest and you can trust them and they do the right thing...it's just better for everybody.
It's hard sometimes but it's the right thing to do.
For me, the right way to make that kind of very personal decision, because those decisions are personal, they're not like data-driven business decisions. They are, "What does your heart say?"
And for me, the best way to think about it was to project myself forward to age 80 and say, "Look, when I'm 80 years old, I want to have minimized the number of regrets that I have." I don't want to be 80 years old and in a quiet moment of reflection, thinking back over my life, and cataloguing a bunch of major regrets.
In most cases our biggest regrets turn out to be acts of omission. It's paths not taken and they haunt us. We wonder what would have happened. I knew that when I'm 80, I would never regret trying this thing (quitting a good job to start Amazon) that I was super excited about and it failing.
If it failed, fine. I would be very proud of the fact when I'm 80 that I tried. And I also knew that it would always haunt me if I didn't try. And so that would be a regret, it would be 100 percent chance of regret if I didn't try and basically a 0 percent chance of regret if I tried and failed. That's a useful metric for any important life decision.
