I knew this would happen...I've only been working 5 days in total, and it's already really wearing me out.

Today wasn't a very good day - half the things I was asked to do I did wrong because I'd never done them before, and even though nobody minded much it made me feel like a complete moron and I was dreading going back after lunch.

It doesn't matter how hard I work - I was told by the manager "don't work yourself to breaking point" when I was still trying to find files for him near the end of the day after most of the staff had gone home - there's always something that goes wrong, it never seems good enough.
It's stuff like this that almost makes me miss school...at least then I knew what I was doing.
