So I just started at this new job just a week ago, but I keep making stupid and careless mistakes. Nothing to do with my knowledge of the subject, just misspelling, typos and even basic printing, like my brain suddenly forgot common sense and basic things.
I'm so annoyed at myself and feel really bad because I ended up making trouble for my supervisor (today my boss lectured her for a mistake I made). This is one of my first real jobs and I would like to make a good impression so that maybe they hired for a good amount of time after my contract ends, but I feel that I'm doing everything wrong.
For a little context I'm working as a file clerk and yes I do check my work before turning it in, just that after i do that and I'm pretty sure everything is rigth I check my work and see mistakes I hadn't seen before.
I really don't know what to do.
