Wombie wombiggity... I have had a full time job since I was a teenager. It has always been a struggle to keep up with simple stuff, but I manage. If you need to find extra time, here are a few things you can do:
1) cut back on tv. Seriously, fuck that shit. You might think you're getting stuff done during the commercials, but you're not.
2) cut back on internet. (I am currently typing this instead of filing for reimbursement for gym expenses.)
3) cut back on sleep. (don't do this)
4) wear your dirty clothes so you don't have to do laundry (its only REALLY gross after a couple months, and it saves you HOURS ON THE WEEK!)
5) do not clean your house/apartment (its just gonna get messy again anyway)
6) cut back on videogames (it had to come sometime)
7) cut back on gym time (whatever, you'll get a little fat, but think about how great it is to have a JOB)

cut back on time with family (they'll learn to cope without you)
9) cut back on time with friends (you can get new ones when they give up on ever hanging out again)
10) cut back on your own basic human needs like showering and shaving (what's more important, getting paid or smelling good?)
