I'm having trouble finding a long-term activity (i.e., painting or guitar for Fine Arts, working out for Phys Ed, practicing speech for Business, playing chess and upgrading items for Technology, fishing for Sci/Med) for the Communications degree. Since the radio transmitter was giving me Charisma, I tried practicing speech, and the degree progress bar dropped. Next was writing, both practicing writing and writing a book. Still no luck. It lists photography as a metric, but there is no way to "fire and forget" a sim to raise that skill.
Has anyone discovered an activity that will work for Communications?
