Kind of a discussion, kind of a sharing among peers in a community, and all around a quick way to maybe help a whole bunch of others while sharing a little bit about yourself. It can be gaming related, life related, or whatever you want it to be.
For me, I have two and they're both geared towards more creative efforts. The first is simply: everything is cliche. What matters is your execution. In other words, don't worry about originality, worry about making sure your execution stands out for being interesting in how it handles what is going on. The second is: anyone willing to suck can create. This is something I tell myself when I'm bemoaning the fact that something I am preparing for game, or for my own works, sucks. Everything sucks starting off, you just got to work from there. It's part of the process.
How about you?
