complete level 3 of the sims

I started playing The Sims for like the sixth time yesterday. The bad thing is that I always quit in level 3 because it gets harder. This is the level where you have to get promoted to levels 4 & 5 in your career and then throw a party where you meet your soon-to-be roommate. However, its hard to throw a good party and balance it out with having enough energy and going to work. My brother is playing right now and he is going to do the following: come home from work, pee, sleep for 2 hours, throw party, become better friends with people. When they leave, do the same the next day. That way I will start making relationships that I will ask to be roommates with.
