It is a kind of job with little sense of achievement.

When you achieve some great success, you may attribute it to your efforts and your intelligence;
but while you are falling down, you are probably to blame it on her or him.
---------------------------

Work as a hard-working and wholehearted teacher; work as a real jerk.

---------------------------

While you are sound asleep in the middle of the night, he or she is still working on for you even though he or she's feeling tired.
Giving a piece of homework means piles of extra work.
Think of you anytime just as he or she finds any good news or gets any information special for you.
He or she cares if you are feeling sick or being in a bad mood; whenever you are in need, he or she is always there for you.

You just come and go ; but he or she still stays for you.

He or she cares so much about you, but what and when will you think of her or him?

Salary is something important, but money is not the payment. He or she needs nothing but your support to give her or him much more courage.
