Need advice or encouragement - I feel like I am screwed for life.

Hello,

I am a new graduate from college in a quantitative field from a very good school. I have an okay resume, but I am getting interviews and have gotten an internship offer contingent upon background check (they do employment, references, education, and criminal background). I just remember when I was 18-21, I did 3-4 jobs, quit them all, by leaving and never showing up because I was a dumb kid (am 25 now). I realized that probably all of these jobs have me as terminated. How screwed am I for my future? I feel like I have no future now because of this.
