Should I Stay in My Job or Quit?

I started as a temp and my manager liked me so they created a new permanent position. My work involves a lot of administrative duties, and next week I will start what my actually permanent position would do. My goal was always to be a Data Analyst but I wasn't lucky to get interviews. I have Computer Science degree and was planning to do my accounting designation this September so I was planning to resign to pursue my career goal. I feel bad for leaving when the job I was supposed to do just started.

Suggestion:

if you're not happy your not happy. listen we spend more time at work than we do in with our family and friends. it's important to like the job you do else you'll not be happy in your personal life.
