Maybe first figure out what you really want to do, that could be a good start.
I'm just going to assume you're new to everything, please don't kill me if it isn't so.
Basically, there's several things you can do. You could try doing all of them, but I wouldn't really recommend this. On the other hand, having a basic knowledge of all of those while focussing on another can really help.
You could do
- 2D art: focusing on textures, concept art,..
- 3D art: For this, you will have to choose a program to model in. There's an excellent free program called Blender (
http://www.blender.org), but there are also payed alternatives as 3DsMax (which has a 30 day free trial). You can find tutorials for these all over the internet, but I would recommend you to pick blender and go with:

3D can be split up into:
- Modelling: I would recommend this when you're new. Get an understanding of the program you're working with.
- Animating
- programming: C++ in this case, you're best doing what they said above this post.
- There are more, but I would just worry about those 3 above.
Don't expect any of these to be easy though, but it certainly helps if you like doing (some of) them.
