Condominiums
The best way of getting somewhere is this: build condominiums.
You get more stars as you get more people. You get more people
as you get more condos. Condos are a sure source of income.
Build something necessary (nursery, elevator, parking, etc) as
needed, but build a ton of condominiums!
