I want to go back to school. I graduated undergrad in 3 years so even though I have a Bachelor's in CS, I still feel half-baked. I studied CS only because I freaking love it and learning more is my utter passion. I want to have a graduate degree in CS... but how? I have a job, I have other stuff to do now, and taking an almost decade investment sounds way too much (in US PhDs can take very long). I'm a very socially awkward dude and spending my entire 20s in PhD almost seems socially "risky". Did someone else have experience on this matter? I have otherwise have the funds and passion to pursue this.
