I've stopped the urge to create repos, buy domain names etc, and started just diving into Sketch to do mockups to flesh out ideas instead. It gives me pause to think about features and to show people to get feedback. You can also use it as a sales tool to sell an app you are thinking of building without investing weeks and months. Nowadays its so simple to do nice mockups its so easy to find stencils for SemanticUI, icons etc. Makes it a breeze to get an interface going and I have never been this productive in the 'idea' stage before.
