This is actually quite simple,pick up a minor that interests you. If you like basket weaving, take a basket weaving minor, maybe you can disrupt the whole basket weaving industry in the future...who knows. What you take as a minor has little impact on your job later in life, unless it's something you really enjoy which will give you some direction to apply your CS degree.
