You need to overcome the attitude that is holding you back. There is indeed a lot of great artwork being done here, even by "noobs" but one thing I'm willing to bet on is that all of these artist spend a great deal of time in Maya. So much so that they'll find themselves trying to "tumble" in other programs.

The one thing I can think of that might help you is to model a topic you have an interest in and set a goals to complete your vision. If you're working on a topic that interest your more inclined to stick with it.

I've been working with Maya for a year now, and I'm still learning just modeling. I keep delving deeper into various option and actions. This for me is fun so that is why I stick with it.

It may be the you're just not suited to 3D work also. If so, there's nothing wrong with that. If this is the case, then just accept it and move on.

Good luck whichever route you go.
