push myself to be what I want

I recently changed job’s and am really enjoying it, so then comes my 3 month review I’m always worried when it comes to work have i done my best,will they know how hard i’m trying,i hope i haven’t done anything wrong that kind of thing and I do my own head in about it sometimes, anyway at my review I got promoted I nearly fell over but it show’s all that hard work paid off and I now have to push myself in this new role to be the best I can be nobody can ask more of you than that.
