Graduate School?

Megalith hit the nail on the head.

Grad school is nice and all, but I'd look in to it after a year or two. Some lines of work give a roof depending upon your education. With a masters, the "roof" is higher or often nonexistent. In my line of work, for example, getting a Masters will boot you up two years on the pay scale... Whereas if you worked those two years, you could potentially be much higher.

My opinion is to just sniff around in the industry before you commit to grad school. You might not enjoy the work at all, and it'd be better if you wasted four years (on average) of your life as opposed to six or seven. It's a "look before you leap" sorta tactic.

Jam it back in, in the dark.
