Is it selfish for me to not want to have kids? Perhaps it is, but if I based my life around what others wished for in me I'd be a Pot smoking alcoholic working a dead-end job that paid for a car I didn't want that would drive me to the job I didn't want to go to to support a wife* I couldn't stand who was raising kids I never wanted.
Oh yeah, Live the dream!
Fuck that, I work a low-paying, but most importantly, low-stress job that has decent benefits. Sure it means I have to make sacrifices, like buying a 30" TV instead of a 72" (insert 'First World Problems' image) and taking the bus or, you know, walking to work instead of driving my own vehicle. But you know what, I'm happy like this, I've got an awesome group of friends and colleagues who I get to spend a lot of time with because I'm not working stupidly long hours, I've even got spare time enough to watch marathons of My Little Pony, go out to the bar for drinks, or hell, take a weekend off and visit my family once in a while. and anyone who wishes to take that away from me can kindly go frag themselves.
*And yes, this part is true, my 'friends' at the time were convinced that this girl and I were perfect for one another and even after the first date (which they set me up on) blew up in their face they kept trying to repair it. It goes without saying that we couldn't stand each other.
