What is one of the best or most worthwhile investments you have ever made — of money, time, or energy?
Recorded Ahmed Zewail said elsewhere, not written here
My science family came from all over the world, and members were of varied backgrounds, cultures, and abilities. The diversity in this "small world" I worked in daily provided the most stimulating environment, with many challenges and much optimism. Over the years, my research group has had close to 150 graduate students, postdoctoral fellows, and visiting associates. Many of them are now in leading academic, industrial and governmental positions. Working with such minds in a village of science has been the most rewarding experience – Caltech was the right place for me.

Katie Taylor Irish professional boxer; Olympic champion 2012
The reason I've been able to keep going for so long is because of how much I love my sport. I still haven't lost that drive. I'm still as passionate about my sport today as I was when I first laced up a pair of boxing gloves. I love preparing for battle and getting into that mindset you must reach when you're putting your body through torture in training camp.

Tadao Ando Architect; Pritzker Prize laureate, 1995
More than 500 children under the age of 18 lost a parent in the Hanshin Earthquake; 88 of them lost both parents and became orphans. I have proposed the establishment of a foundation in order to support the education of these children so that they can sustain their hopes for the future. To that end, I would like to contribute the hundred thousand dollar prize awarded to me today by The Hyatt Foundation towards this new foundation for these young earthquake victims.

Yaa Gyasi Novelist
The desk helps, now that I have it. I’ve stacked piles of books that I love on it to act as talismans. They help, too. The desk makes me feel like I’m going to work, even though work is located in a cramped but bright corner of my living room. […] I used to think of myself as someone with a great deal of discipline, but I lost it in the air somewhere over the Rocky Mountains. Now, instead of discipline, I have a desk, and every day that I sit at it I dig a little deeper.

Warren Buffett Chairman and chief executive of Berkshire Hathaway, 1970–2025
We've just passed a milestone: Twenty years ago, on January 3, 1972, Blue Chip Stamps (then an affiliate of Berkshire and later merged into it) bought control of See's Candy Shops, a West Coast manufacturer and retailer of boxed-chocolates. The nominal price that the sellers were asking - calculated on the 100% ownership we ultimately attained - was $40 million. But the company had $10 million of excess cash, and therefore the true offering price was $30 million. Charlie and I, not yet fully appreciative of the value of an economic franchise, looked at the company's mere $7 million of tangible net worth and said $25 million was as high as we would go (and we meant it). Fortunately, the sellers accepted our offer. The sales of trading stamps by Blue Chip thereafter declined from $102.5 million in 1972 to $1.2 million in 1991. But See's candy sales in the same period increased from $29 million to $196 million. Moreover, profits at See's grew even faster than sales, from $4.2 million pre-tax in 1972 to $42.4 million last year.

Question When you feel overwhelmed or unfocused, what do you do? Daily life
Arriving in the States, I had the feeling of being thrown into an ocean. The ocean was full of knowledge, culture, and opportunities, and the choice was clear: I could either learn to swim or sink. The culture was foreign, the language was difficult, but my hopes were high. I did not speak or write English fluently, and I did not know much about western culture in general, or American culture in particular.

Question What is an unusual habit or an absurd thing that you love? Daily life
The great singer Um Kulthum (actually named Kawkab Elsharq – a superstar of the East) had a major influence on my appreciation of music. On the first Thursday of each month we listened to Um Kulthum's concert – "waslats" (three songs) – for more than three hours. During all of my study years in Egypt, the music of this unique figure gave me a special happiness, and her voice was often in the background while I was studying mathematics, chemistry… etc. After three decades I still have the same feeling and passion for her music.
