Navel-Gazing Panic Attack

So I've been getting really excited about the idea of doing a political humor comic strip about the lives of young (mostly broke) 20-something Brooklynites, but I had this sudden worry today:

Is that just navel-gazing?

Sure, the cast would be of various sexual orientations and ethnic backgrounds, and it would have a decidedly feminist emphasis, and would be about things that are weird or funny or ridiculous, but...

Yeah. I'm still going to do it, but I have to think about this. The characters should be ordinary enough to relate to but eccentric or extraordinary or funny enough to be interesting. At the same time, I reject the idea that all comic strips should be about amazing huge events that change the world or overblown superheros or absolutely nothing and I also think it wouldn't make a huge amount of sense to do a strip about characters I don't at all relate to--the whole point is an outlet for some funny stories and ideas I have about my peers.

Hmm... well, at any rate, I promise it will be interesting. I think the main thing is creating memorable characters with distinctive personalities (as in Bloom County or Calvin and Hobbes).
