When I was deciding whenever to keep the kid or not when my girlfriend got pregnant I realized that all the things I couldn't do with kid I wasn't doing anyway, because I wasn't motivated and focused, and ironically, later when I got a kid I did lots of those things after all. Having someone who depends on you makes you focus on what matters. I mean you can always be a lying ass but if you're even remotely honest and have a bit of shame, starting a family is amazing accountability method.
