CAD Position

I always have the passion on computers. I can work hours without stopping, but still enjoying it. I was thinking that I should have taking a computer engineering course when I was in college because that is what I am passionate about this days. I know a little bit of it, but it is so hard to apply for any CAD jobs if I do not have the broader knowledge for it. I just do self study, but still I felt like it is not enough to really get a job. My degree is on accounting. It is so far from my passion with computers. It does help in some ways, but I need a broader view or knowledge on this field in order to be more confident in applying for a position. CAD jobs are complicated at times if you not have the knowledge. It has a lot of terms that only a CAD expert can tell what it is. I want to be like that, I want to be an expert so that I can prove that I know what I'm doing just in case given a chance to be hired.
