Scratch is a place to learn the basic principles of coding, such as variables, lists, functions, etc. It isn't a place to get famous. If you want to get famous, actually LEARN from Scratch, then move on to something more advanced such as Roblox, Unity, Unreal Engine, or Snap! If you just want to learn Scratch in your free time for fun or just for the sake of knowing another language, that's fine! Remember, knowledge IS power! (sounds cringey, but it's true) Scratch is about learning and having fun! A good way to learn if your just starting out is to watch tutorials or look in other Scratcher's projects and try to understand what the code is doing. (Tutorial tip: Watch tutorials where someone actually explains how the code works. If they are just giving you all the code and not explaining it at all, that's completely pointless because you don't learn anything from it.) It's ok to WANT to be famous on Scratch, it's just not okay to let that take away from your fun and learning. Make projects that YOU want to make, not projects that you know OTHERS will want to see.
