What's the best way to make money in Tiny Tower?

This game I found to be interesting. Making people happy is easy - give them their dream jobs. This only helps to give you a few extra TowerBux. To make money and more floors, simply build a residential floor, and look at the people in there once you add them in. Lets say 3 have creative personalities or higher levels in creativity. Make a creative floor next. Keep checking the app every 15 minutes or so and keep restocking every store. Having fully restocked floors will give you extra cash and TowerBux.

It takes AGES, let me tell you. I have 107 floors and it took months. Just be VERY patient and continue stocking as much as you can.

Don't be afraid to evict tenants who don't offer enough skills, or delete an unprofitable floor to replace it with something better. Both of these actions will take time, but not cost money. I've also found that getting two or three workers on each floor gives me money faster than having more floors, so make sure you build plenty of apartments.
