How would you feel if I tell you that I ended up getting me fired from my first job?
Ouch, that's terrible news. What got you fired?
My boss thought I wasn't working hard enough
Well, if you weren't working hard enough it makes sense that he fired you.  It's part of his job to make sure people who aren't contributing are terminated.  I hope you learn from this and work harder next time!
No I don't want to work harder than I'm doing. It's the managers responsibility to manage me better so I don't fail.
It's sad that you got fired, and you should really think about how to improve your work habits so that this won't happen again in the future. Perhaps the shifting of blame is due to the fact that you despise your job. I bet if you find a job that you are passionate about, you will be one of the hardest workers I know.
