I have experienced creating products. For me, "just ship it" is a totally wrong advice to give, in the same way as "we will ship is when is ready"(and never is ready). You have to plan ahead, know your limitations and say NO to adding things you can not complete on time. And you have to plan for things that look simple being much harder to implement in practice. You need discipline for saying no, and it is not as funny as just trying new things all the time(new languages, new platforms, new methodologies, new projects). But you are an adult, not a kid, you should be able to control yourself(and most people can't BTW, they drink coffee and smoke because they need external controls instead of internal). You should try new things, but not too much. It takes time for being efficient and master something. There are diminishing returns too but productivity while learning something new is almost zero compared with the master. How much is too much? It depends on your specific job. I recommend people to write down and document the actual real work that something takes on calendars and their expectations. Over a period of time, you will be able to compare your expectations to your actual work in detail. You will surprise yourself where you spend most of your time. Then you will be able to take decisions and say NO to those areas that take most of your time and give you back little on future projects.
