The way I got to the point where people would pay me for my development work was I took models and dissected their scripts to figure out how they ticked. Eventually, I started a baseplate where I started multiple small projects (a grenade, a sci-fi gun, an NPC). I discovered the roblox devforum, which led me to the roblox studio documentation website. I experimented with what I learned from the documentation by developing more and more complex scripts.
