What do you wish existed and build that? Oh, it's too big? Build a piece of it. Oh, that's too big? Build a piece of it. The problem you're probably having is that you're saying, "I want THIS" and THIS is too big for you to imagine. So, just write a small subset, maybe 3% of that. Then you'll realize you can easily build this next little bit over here or over here and eventually get there.
