Preparing the presentation: Does it worth it?

I'm not sure if it's just me but when I was preparing my presentation for the ESA Annual Meeting, my characters resulted to me so insignificant... it was like all the time I've spent looking at the weevils trying to find characters, recognizing character states, coding, analyzing, thinking about groupings, distributions... in some point all turns so light... as if all the work was not really saying anything...
But you need to stop... if the characters are not which/what you expected, there are several factors influencing your results, but most of all, THOSE ARE YOUR RESULTS and there is nothing you can do about it, just to try to present it as down-to-earth as you can, and in such a way that you feel comfortable with what you are saying and how you are saying it.
