Casting my vote for continued optimism! I’m feeling the same way, Munchkin – I’d like to be able to celebrate successes, both mine and those of my fellow ADDers! I guess that’s not much of a shock, given that I’m always looking for high fives! 
I actually even worry that venting about my own difficulties might offend people, since as a rule they’re not all that earth-shattering compared to what others here are going through.
I guess in the end we just have to stay true to ourselves, respect others, and hope that somebody out there appreciates what we have to say.
Heck, even I change from day to day; sometimes I am motivated by others’ success, and other times – and this sounds sort of mean-spirited – by their failure, only because, well, it lowers the bar: “I can CERTAINLY do better than THAT.” (Trust me, I would never say that out loud! ) So for me, it’s actually helpful to have an array of outlooks to choose from, depending on what I need at that moment.
