The game contains a lot of intracate connections, similar to the real world. Resources are limited and one must plan a strategy for meeting their objectives. A couple of key starting points, minimize the roads, these take up space that a building can use, save money so that you can afford the best infrastructure. This is difficult at first, but realize that you will ultimately reach a point where you are demolishing the cheap ones and replacing with the best. Build storage as you grow, don't wait until it stagnates you. Use landmarks, education, entertainment, etc buildings wisely choose high percentage population increases with the smallest foot print. I started with the low key ones and ended up replacing them all, skip the replacement step! Good luck building
