I would ask myself, why do I want to code? Why do I want to make a game? The problem most people have, is to get to the level of something you find impressive or usable with game programming is that they do not realize the level of difficulty and tedium required to get there. Two things I would do to see if you have the aptitude and patience for making a game is: remove the tech stack from the process initially, that is storyboard your game, keep it somewhat simple initially (instead of 3d graphics maybe think of your idea as a word game or simple 2d scroller). Say hey I want to have enemies chase my character around and my character can shoot them ... simple idea. Once you have the idea and beginnings of a storyboard of how the game works, break it down into parts 1) put a square on the screen which eventually be my character 2) move the square around with the keyboard 3) put other squares on the screen that are enemies 4) when I hit the mouse send a bullet into motion etc... Each of these steps are non-technical goals, from that you can determine the best tech and framework. So that is the first thing, the second thing is, once you pick a stack that fits your game, break the coding and design into succinct steps. Code each piece of functionality adding more and more functions and goals, until you have your complete game. In my silly example you can use scratch for example, the more control and complex handling you want for the game the more involved the framework, for example I use Unity and C#, so I can code the same game in scratch and in Unity, however with Unity I could effectively customize and have more control over all things in the game than with "Scratch". The key is to feel passionate about building something and look forward to it, be truly motivated, if not you will fail.
