Is a 7 minute time good for someone who's only ran a mile twice?

So for reference my local grocery store is a mile away from me so I use it to track my progress. Ive only ran a full mile twice and I'm averaging about 7 minutes on my time.

I'm 30 and I just recently started trying to get into running more. I usually play DDR as my cardio and I just want some advice on how I can shave my time down to 6 minutes.
