Working in Chinese takeaway

Nice to be a counter in a Chinese takeaway,
No worry about the life expense any more,
Take 4 days out of 7 in the job,
But lost some study.
The subjects become more and more difficult to me,
Because it is more complex than last time,
I'd prefer pay more time in it,
But came back too late,
Wake up so early to catch the early bus.
I feel no a second would be waste,
Many things waiting me to do,
Of course, I will conquer them.
