Every new year of the last decade I set a personal challenge. My goal was       1       (grow) in new ways outside my day-to-day work running Facebook. These       2     (lead) me to learn Mandarin, code an AI assistant for my home, read more books, run a lot more, and get       3     (comfortable) with public speaking.

When I started these challenges, my life was almost all about building the Facebook website. Now there’s so much more to learn. At Facebook, we’re building lots of different apps and technology and we’re handling a lot more social       4     (responsible). And   outside Facebook, I’m a father now and I love spending time with my family, working on our charity and improving at the sports and hobbies I       5     (pick) up over the past years.

This decade I’m going to take       6     longer term focus. Rather than having year-to-year challenges, I’ve tried to think about       7     the world and my life will be like in 2030 so I can make sure I’m focusing       8       those things. By then, if things go well, my daughter Max will be in high school. We’ll have the technology to feel       9       (true) present with another person no matter where they are, and scientific research will have helped cure       10       prevent enough diseases to increase our average life expectancy(平均寿命) by another 2.5 years.
