It is hard when they are such close languages! But maintaining is always hard. I compare it to building with clay while it's mildly raining. You need to keep re building chunks that fall off what you've built. Eventually some chunks dry enough that they are solid forever and you use them as a base to keep going. I don't think you need to put a lot of time and effort in maintenance but you do have to put some with certain regularity
