To self publish or not, that is the question

I have a good amount of my book written, however, I am uncertain whether I should self publish or pitch it to a known publisher. I have done some research and found that self publishers do get their writing out there and do make money, but I am still conflicted about whether I should do it. If anyone has ever self published or knows someone who has self published, I could really use some input and advice. I am nervous either way and could really use some guidance.
