I would strongly advise that you pick a stack, and then build a library or repository that you can clone in order to easily make new projects and push them to Heroku. You're probably going to think of dozens of things it would be neat to work on. If you have to spend a week each time you start a new project before you get to the interesting part, then you're much more likely to just give up. If you can have a new website online in 5 minutes with free hosting, https, user auth, a database, and a basic frontend, then you get to have fun doing the interesting parts. I did this with my current stack of choice (.NET Core/VueJS), and left myself directions for getting a new project going: https://github.com/caseymarquis/QApp https://github.com/caseymarquis/QApp
