You speak a bit german?... that's cool! Not because german is a nice language but because it's hard to learn.
Never give up your dreams. A lot of wonderful things is possible if you stay focused and learn day by day. my dream as teenager was to become an 3D artist because I was very impressed by the first 3D animated movies and computer games and would create those things for my own. And a few years later this dream became true. The most things I know about computer graphics especially 3D I've learned as an autodidact. I sat hours and hours in front of my PC and learned step by step. Most of my friends at this time didn't understood that I've did what I did. But I was so fascinated by the possibilities to create everything I would on my computer. Ok... I'm talking too much. The point is... stay tuned, work hard and you will reach your goals.
