Let's put it this way....
I know of a number of diploma holders who earn under $2k. And they
work full-time.
The way I see it, earning an extra $500 per month in return for
increased travelling distance is a very good trade-off. Shucks man,
I would willingly take on an internship that pays $500 per month
even if the company's all the way in Tuas (I live in Marine
Parade).
Just be glad with your good fortune, for not many others share your
fortune.
