My Job and My Career

I had studied accounting in college so naturally, after graduation, I then worked for 7 years as an accountant. It was both my career and my job. However, for financial reasons, I then changed my job to another one in the IT field. Now, after spending 3 years in that new job, even if I had a better offer, I believe that I will not work as an accountant ever again. So, I think that it means that I not only changed my job, but I also changed my career.

Good job! I easily understood everything that you wanted to convey to me as the reader. While there were no major grammatical mistakes, I just reworded / rewrote your text to make it sound more natural. I hope this helps you. J.
