Lots of comments here on keeping this as simple as possible and not over-architecting. This is a good value, but its equally important to add architecture and abstractions before its too late. Software projects become tangled spaghetti messes slowly, over time, by adding "just one more thing" to existing modules and functions until they are large and impossible to fully understand. My simple rule of thumb is this - no file should be longer than 300 lines of code and no function should be longer than 15 to 20 lines of code. If your file or function is longer than these guidelines, its trying to do too many things and its time to break it down.
