You are good enough. It's not that you can't do projects. You just can't do projects of a certain size. Games can be tough at first as there's lots of things going on at once, and you could be trying to write a novel before being fluent in your ABCs. Get used to finishing what you meant to do. Before starting a project, plan to finish it. If you can't finish, rescope it. You get experience for each project you finish, so the optimization is to finish more. Decide how much time you have. Then set a schedule, one that you can commit to. You can have a roadmap, set out to deliver things per release. Or just say you're done with it and do something else. With sufficient experience, you might decide to make higher quality projects in full. Or you can keep incrementally increasing the ones you have.
