With over 363,000 downloads at ModTheSims, the Self-Employment Career Mod is definitely one of the popular ones in the Sims community. This mod is created by Neia, an active mod maker with many other career mods included in this list. This mod mainly fills the career panel for self-employed Sims when asked what they do for a living. I like this mod because it undoubtedly adds something valuable and unique to the game. It is unavailable in the basic game. Give this mod a chance too, and it is really worth a try! You only need just the base game to use this one. You may download the file at ModTheSims.
