Just be patient and hopeful. Start with what you are comfortable with and slowly experiment with new features. It doesn't even have to be a game, it could be an demostration for yourself.
I sometimes feel discouraged by these awesome 3d box whatever examples random people post here, with crazy math and whatnot. But really, just do what you know, and perfect it. Starting with small projects is key to getting your foundations. I mainly stick to platform games because 1. I find them easy and 2. I enjoy them! So don't feel like you have to have some complex mammoth game to make everyone go "OOh and Ahh!" It's usually the more simple games that are more enjoyable!
Hope this helps Caspis! Peace!
