Welcome to the Adult World

In the christmas dinner, my boss wish me 快高長大...
Side meaning, hey pls grow up...a friendly reminder.
When I moved here, I started to feel that I have a big gap to fill. I really feel myself too young, too 衝動 and have too many comments, and these charactors did bring some negative consiequences to my work.
Yes, time to grow up a bit.
