Sorry, I'm also going to harp on what everyone else is: grocery bills are 400, restaurants are 300, and staff dinners (not sure what those are, exactly. If they are discounted meals from where you work, then your grocery bill should drop a bunch.) are 200. That means 900 a month on food! And just one person?!?
I have a family of two for 400 groceries (which I know some people on here still think is high), and about 50 on restaurants. So cut out staff dinners and reduce restaurants to like 2-3 times a month, and you're from 900 to 450. So a savings of 5400 a year right there. So expenses go from 38400 a year to 33000. Plug that into the networthify calculator, and I bet you'll see at least a year come off. Half your entertainment costs (by going outside, go to free concerts at a local college, free movies, books and videos games from the library, etc.), and you're down to 30,000.!
Definitely worth it in my opinion.
