For those that have University...create a sim. Have that sim achieve all 6 degrees and reach the top of a career in each of those degrees. For example: Once your sim has obtained, say the Fine Arts degree, have them reach the top of the Culinary or Music career. Then go on to another degree, and have them reach the top of a career in that degree...and so on. I have been working on this for a long time, trying to figure out which one is the best one to achieve first. I definitely would go with the following three first: fine arts, technology and science. These degrees give you a good base of skills that open up many careers. But, it is up to you how you wish to achieve this lofty goal. At the end of the challenge, not only does your sim have a lot of skills, but you've earned yourself a badge on the Sims 3 game.
