I am interested in retracting my old journal articles. Would it have any negative effects on my academic career? I managed to successfully publish my old bachelor thesis in a good quality national journal in my country. However, I am thinking of retracting the article due to certain circumstances. First, I felt really embarrassed by the low quality research methodology used in my bachelor thesis. I only used simple correlation in my research. After it was published, I realized that the journal editor team forgot to include a reference in that article because they were rushing me throughout the editing process. I informed them about their mistake and it seems that they have done nothing to fix the problem. I became a bit annoyed because the editor team has never made this problem in the past.

I felt that it would be better for me to simply ask for retraction to solve this issue, but I am a bit afraid of negative consequences in the future. Is it okay to do this? I am really interested of entering the academic world in the future.
The way to "retract" old work is to publish better work that references the old work and its errors. There should be nothing embarrassing about having found earlier errors and correcting them.

You have grown in the interim. Every active academic will likely have such an experience at least once in their career. The earliest work was done when you were, relative to now, somewhat inexperienced. 

It is unlikely that they will retract the article for the reasons you give, but it is also possible that someone else will publish a better work based on your article. Your best course, I believe, is to publish it yourself.
