too much focus on failure?

I went away a couple of weekends ago with some friends, and we had some amazing conversations among the madness that is the guys cabin weekend.

Coming out of that time of conversation i have been thinking do we dwell too much on those things we cant seem to get past, and not enough time thanking God for the things he has helped us conquer.

i wonder if so much of our heartache comes from looking too closely at where we fail, and not looking closely enough at our successes. I am going to look and focus on where God has matured me and where he is having victory in my life, maybe this is how we overcome through looking toward what is good and admirable, and not living in the regret of our mistakes.
