The same is true of filmmaking as well. You have to practice to get better. You don't even need formal training (just like video games; though, as in both, a few pointers now and then can certainly help). You need to become familiar with your tools. You need to hone your skills.
So, take a break from your hours of video games this summer and spend a few out shooting some footage. That practice will make you better when it comes time to shoot one of your projects.
