Remember write down all the jobs you have done for your 东家。including every large and small project.
"-- Successfully designed ABCDEFG... on budget on time..."
This is a good chance to do your Show and Tell, and put it on writing.
For the improvement part:
"As a professional, I will try my best to catch the advanced technology in this field while I am doing the project for the company....."
And list whatever the boss asked you to do for next year.
The goal of this review is get $$$ raise after that.
Thanks!
