Mental Mistakes

I try to not make mental mistakes very often.  I'm not egotistical but I do know I am good at what I do.  Sometimes I get a little bit of a big head and it gets me in trouble.  Other times, it is just my constant ripping and running and lack of rest that leads to detrimental judgement calls.  Such was the case at work.  The past two weeks I have made some very careless mental mistakes.  No one was harmed in the process but unnecessary attention was put on myself and my peers.  Due to this, I've been given a vacation from work aka a suspension.  I don't know what the future holds.  I just know that if given another chance, I can't make any mental mistakes.
