Don't worry, when I was a fresh grad (I have Bachelor and Master degrees) at age 22, I also earned 1萬, before I become a full-time housewife (age 29), I earned much more lah.
Remember to change jobs often ah! Only change jobs more often can give you a bigger salary increment (10-30%). I changed job every 1-3 years.
I have a friend who graduated from a quite well-known UK Uni at age 22. He's now over 42 la, but earn only 20k+. You know 20 years ago U grad is very 吃香 ga ma. So how much you earn really depends on 際遇.
