Fired from job before changing industry - how to overcome?

I couple of years ago, I was fired from my job for performance. The job really wasn't a good fit even though I stayed on it for 2 years and had some accomplishments. Had some disagreement with management. Basically I wanted to do a different kind of work, which I had tried and was good at, but they wanted me to do the same repetitive work which I wasn't built for. At some point I just got too tired of the job and wasn't trying anymore. While I was looking for other opportunities, my employer fired me, and a few months later I found a job that I loved and has been doing it since. I know it was my fault that I got fired. I should not have tried to stay on the job for that long, and I should have tried to keep things under control while looking for a new job. But it happened, and I've learned lessons from it. I'm planning to apply in 2017, and I wonder how I can overcome the termination for my applications. I know that I'll have to explain the employment gap and the termination since many schools explicitly ask for it. If there are schools that will reject me simply because I got fired, I'd like to know what they are so I won't bother with them.

Any advice is welcome. Happy New Year to the mbaMission team!
