2019 Annual Summary

On September 15, 2017, the first day I joined the company, I told myself that I joined a good company which has a good treatment but I was not feeling happy at all. I had plenty of worry and confusion at that moment because I didn’t know my direction.

All I can do is working hard and learning as much as possible.

At the beginning of 2019, I told myself that 2019 is crucial for me. I must do something that will allow me to seize the opportunity that gives me a clear direction.

Time flies and many events happened in 2019. Maybe it didn’t meet my expectations, but fortunately I didn’t feel regret.

Today is January 1, 2020, it’s time to make a summary.

Annual Targets

Unfinished Targets

  • Read Lua source code

    I didn’t finish reading the code, I only read part of it. But it’s a start, I have started to understand some of these principles.

  • Finish OpenGL tutorial

    I didn’t have time to learn it since I didn’t finish reading Lua source code.

  • Read 10 books

    Only 6.

Finished Targets

  • Memorize words every day

    I did it.

  • Finish reading CLRS, and then read TCP/IP Illustrated

    I did it. But the translation of TCP/IP Illustrated is too bad, So I read Discrete Mathematics and Its Applications instead of it.


I kept remembering words every day and completed daily plan every day except June 22 due to too busy that day to finish the plan before 00:00.


I have been remembering words for 605 days. I’m not good at language learning and I used to hate English. Nevertheless, for programmers, English is essential and it’s a basic skill. I have overcome many difficulties and now I can read English articles more easily. In the future I hope I can hold on and improve writing and speaking skills.


  • I finished reading CLRS except the last two chapter due to I didn’t have enough mathematical knowledge to understand it.

  • I read about 1/3 of Discrete Mathematics and Its Applications.

  • I have been doing algorithmic exercises on LeetCode since June. It’s difficult for me, but this is the beginning.

  • I built my tech blog and wrote 17 posts.

  • I have been contributing on GitHub since September, it taught me a lot.


    I hope it’ll be full of green spots in 2020.

  • I read part of Lua source code following this guide. I have understood some of these principles.


I read 6 books in 2019.

  • The Tale of Genji
  • A Tale of Two Cities
  • Notre-Dame de Paris
  • No Longer Human
  • The Romance of the Three Kingdoms
  • Journey Under the Midnight Sun

The two books that impressed me most were Notre-Dame de Paris and Journey Under the Midnight Sun.

Something Happy

On November 9 I attended the LisAni! LIVE Beijing concert and met Nitta Emi. This is my happiest day in years.



The most comforting is that I still love programming despite I graduated from college over 2 years. I feel so happy: what I work every day is what I love. I hope to keep it like this in the future.

I hope to make some changes in the future, I hope I won’t feel confused in the future.

Hello 2020. It must be a new beginning.
