2025 年可能是我人生变化最大的一年。换方向、搬到美国——这些事要是分散在几年里也许还好，但都挤在这一年，真的是有点应接不暇。
职业转向
今年最大的决定是换了方向。从之前做的图结构、infrastructure 这些，转到了算法方向。
这个决定其实纠结了挺久。之前的方向做了好几年，积累了一些东西，团队也熟悉，继续做下去应该会比较顺。但总觉得少了点什么——也许是新鲜感，也许是挑战。疫情这几年，每天都在重复差不多的事情，感觉自己在舒适区待太久了。
转到算法方向，等于是重新开始。很多东西都要从头学，很多人都要重新认识。刚开始那几个月真的很难，每天都有新问题，每天都在学新东西。开会的时候经常听不太懂大家在说什么，技术讨论也插不上话。那种感觉有点像刚毕业，不知道自己能不能做好，但又忍不住想试试。
现在回头看，这个决定是对的。虽然过程很辛苦，但这几个月学到的东西，可能比过去一两年都多。而且这种”不确定性”反而让人更有动力。每解决一个新问题，都会有那种久违的成就感。
搬到湾区
年中的时候 transfer 到了美国，在湾区开始了新的工作和生活。
说实话，决定搬过来的时候想法挺简单的——既然要换方向，不如彻底换个环境。当然，也有想看看外面世界的想法。
Landing 的过程比想象中麻烦。签证、搬家、找房子、办各种手续，每件事都要花时间。刚到的那段时间挺焦虑的，人生地不熟，连去超市买东西都要导航。慢慢适应了作息时间、交通方式、生活节奏，才算是稳定下来。
工作上倒是没有想象中那么大的变化。一开始还担心时差问题，后来发现湾区的时间和国内正好是反着的——我这边早上正好是国内晚上，我这边下午正好是国内早上。反而因为这个时差，和国内团队的配合还挺顺畅的。很多时候，国内同事下班前给我发消息，我这边起床正好可以接着处理；我这边下午的进展，又正好赶上国内早上的会议。
生活节奏其实和在国内差不多。周末也会出去走走，看看不一样的风景。最大的感受是，换个地方生活，会让你重新审视很多习以为常的事情。
2025 总结
这一年变化挺大的。换方向、搬到美国——每一件事单独拿出来都够折腾的，全挤在一年里，真的是有点应接不暇。
有焦虑的时候，担心做不好，担心选择不对。但更多的是期待——期待新的生活，期待新的挑战。
三十多岁了，本以为生活会越来越稳定，越来越按部就班。没想到这一年比刚毕业那几年还折腾。但也正是这些变化，让人觉得还活着，还在成长。
展望 2026
工作上，希望能把算法这块搞得更明白些。现在还是半懂不懂的状态，得多花时间。
生活上，继续适应湾区的节奏，多看看外面的世界。
博客的话，希望能多写一些。不一定都是技术文章，记录点生活、想法也挺好。多年后回头看，这些文字应该会很有意思。
2025 折腾够了，希望2026 能稳一点。
English Version
2025 was probably the year with the biggest changes in my life. Switched career directions and moved to the US—if these were spread across several years it might be manageable, but all crammed into one year has been quite overwhelming.
Career Pivot
The biggest decision this year was switching directions—from graph structures and infrastructure to algorithms.
This decision took a lot of deliberation. I’d spent several years in my previous direction, built up some expertise, knew the team well. Continuing would have been the safe path. But something felt missing—maybe it was the novelty, maybe the challenge. These pandemic years, every day felt repetitive. I’d been in my comfort zone too long.
Switching to algorithms meant starting over. Learning many things from scratch, meeting new people, building new connections. The first few months were really tough—new problems every day, constantly learning. Often couldn’t fully follow discussions in meetings, couldn’t contribute much in technical debates. It felt like being fresh out of college—not sure if I could pull it off, but wanting to try anyway.
Looking back now, it was the right call. Though the process was hard, I probably learned more in these few months than in the past couple of years. And this “uncertainty” is actually motivating. Every time I solve a new problem, there’s that long-lost sense of accomplishment.
Moving to the Bay Area
Mid-year I transferred to the US and started a new work and life in the Bay Area.
Honestly, the decision to move was pretty straightforward—if I’m going to change directions anyway, might as well change the environment completely. And of course, there was curiosity about the outside world.
The landing process was more complicated than expected. Visa, moving, finding housing, handling various procedures—everything takes time. The first few weeks were quite anxious. Unfamiliar place, even grocery shopping required GPS navigation. Gradually adapted to the schedule, transportation, pace of life, and things stabilized.
Work wasn’t as different as I imagined. Initially worried about time zones, but turns out Bay Area time is perfectly opposite to China—my morning is their evening, my afternoon is their morning. Because of this time difference, collaboration with the China team actually works quite smoothly. Often Chinese colleagues send messages before they leave work, which is right when I wake up; my afternoon progress updates align perfectly with their morning meetings.
The pace of life is actually similar to China. Weekends we go out and explore different scenery. The biggest realization is that living in a different place makes you re-examine many things you took for granted.
2025 Summary
Quite a lot of changes this year. Career pivot and relocation—each of these alone would be significant, but having them both in one year has been quite overwhelming.
There were anxious moments, worrying about not doing well, worrying about wrong choices. But mostly there’s anticipation—anticipating the new life and new challenges.
In my thirties, I thought life would become more stable, more routine. Didn’t expect this year to be more turbulent than the first few years after graduation. But it’s exactly these changes that make you feel alive, still growing.
Looking Ahead to 2026
Work-wise, hoping to actually understand algorithms better. Right now I’m still figuring things out.
Life-wise, continuing to adapt to the Bay Area rhythm, exploring more of the world.
For the blog, hoping to write more. Not necessarily all technical posts—recording life and thoughts is good too. Years later, these words should be quite interesting to look back on.
2025 was chaotic enough. Hoping 2026 will be calmer.
