To work is to survive. Of course, it's not the whole truth, but it's a very good part of the reality.
If you got a job like most of us, the salary will be given to you periodically, at least hopefully. However, there are so many auto-pay request, there are so many bills of all kinds which will follow nearly immediately after your salary comes into the balance.
So the salary is just like a pulse in your bank account, the balance will jump up suddenly, but then it will go back to normal level fairly soon.
If you think that you are working for the pulse alone, you will be very likely to lost interest about working or even your life... Therefore, one should learn to enjoy our work, as well as to appreciate what we have behind all those payments - your family, the happy faces, your toys, and more importantly, try to help the needy!
It's not just a pulse.
