Not to be rude OP but I share some of Anon's worry. Game development is one of the most competitive fields out there. I'm unfortunately playing catch up at the moment, as I only decided on game design about 18 months ago. While I may be working on a business management degree, I spend every free second I have, learning a new skill, tool, or reading a new text-book. I've spent many a night modelling for 12+ hours. I've spent entire weeks during breaks learning within a variety of disciplines. Playing with different engines, writing and testing design docs with friends, playing with level design, testing simple games in public places, pushing my limits with my modeling skills, (trying)to learn sound design, reading literature, learning composition, anything that could ever be of assistance. While I may be a passenger in your boat, not being a fan of programming or scripting. I'll be jumping ship soon, diving into anything I can get my hands on. Every language you can learn, any morsel of information, is another tool you can use to create games for your players. These tools allow you to give the player the experience you first envisioned, and that is exactly your job. You are a creator, you are God within your creations, give it the attention god gave Earth.
No knowledge is worthless, and every bit will help you in such a vast multi-talented industry. As i have gone to different conventions, I've seen how devoted these people are to their work. You can see their love of the job illuminate the room. If you want to get anywhere, match that love and devotion. Work on your skills as much as possible. Your art is a part of you that you give away to others. It deserves more than an hour or two a day.
