Basically, in addition to just doing the heists, capers, assassinations, or other immediate criminal activities, the PC group also has to target other groups to increase their reputation, manage a cohort of NPC's lackeys, maintain and expand a hideout, and move into neighboring territories to increase opportunities. This is on top of doing some abstract bookkeeping of resources, including deciding what you want to keep in liquid assets and what you want to sock away for your PC's eventual retirement. Oh, and while you're at it, make sure that each PC spends some time engaging in whatever their vice-like activity might be in order to help relieve stress.
