Second, use Uber Mode, it may be expensive, but it's worth using to not worry about placing Supply, Service, and other important stuff.
Third, use manual buildings, you can use your own buildings you made if you wanna be happy. Just follow the first tip because, for reasons.
Fourth, think about what you are doing right now, are you crumbling your city? Are you actually doing something good for once in this game?
Fifth, make your citizens happy, if you don't put buildings necessary for your city, get ready to be rekt.
Sixth, take some "constructive criticism". Always seek for help, and always follow for help. This can include: feedback, suggestions, criticism, and praise. Don't just add everything people suggest, you aren't fixing the problem. Most feedback, suggestions and criticism is not correct, try to understand what they mean. And fix the problem right away to not have more problems
Take your time and understand these rules, because I'm not actually correct, you could just make a city and that's it.
