Personally, I think our definition of success changes as we age.....for most of us anyway. I hear some guys with kids that hunt say, "Now, just seeing my kids get to hunt is enough thrill for me. I don't even need to actually hunt to feel the excitement."
I can remember a time when I needed to not just kill, but kill alot to be satisfied. Now, I'd like to take a limit, but it seems that I'm satisfied with just being out there. Yeah, going bust several days(or weeks) in a row is sometimes disheartening, but I'd rather be on a hunt, with no kills, than not go on a hunt at all.
Do the poll, and answer honestly.

I'll tell you now, I answered "I have to see and/or shoot only a few ducks to be happy." I'm not to the point where I can go time after time without shooting or seeing ducks and be okay with it. If I ZERO several times in a row, I become disgusted. Maybe one day I'll be able to accept that no matter what happens, I'll be happy. For now, my definition of success is connecting with my quarry at least once every 3 or 4 outings.
