im sort of in the same situation.
after college, i got progressively better jobs.
i probably spend half my post tax income. dont ahve a gf, and well in my case i have a nice computer i bought a brand new car in cash, and i bought a big ass tv. without a girlfriend to set money on fire for, just save the money.
im sure you'll need it at some point .
be it some investment oppurtunity, someday buying say real estate, or i dunno maybe you do end up with some woman , or want to go to grad school , having a lot of money sitting around is not a bad thing.
with people like me and you saving we could i dunno get that national savings rate above -2%!
i suppose you guys who are saying if you just keep saving it and never "need " it for something then what do you do?
well i figure if i ever run into that situation 10 years down the line well... ill just buy a ferarri or something.
