Maybe I read it wrong (tone of voice sometimes is hard to comprehend using texts) but from what I've read of everyone's posts and your responses it sounds like you've already made up your mind because it seems that you got a bit defensive...

Also you're not telling us what job you're currently doing so it's making it somewhat difficult to relate to a job with no advancement opportunites or promotions...

Either way I'm going to have to agree with pretty much what everyone else has said... If you don't want to quit your current career and it wont interfere with your current career's hours or production then go for it... I see no problem in putting yourself in a position for possible advancement in another career...
