I agree with what is said Luke and  Karanta. However, remember this if you decide to produce 3D content:

• To make a salary, this is not a game but a real job that requires hours and hours behind a screen.
• Be prepared that a product is a real flop despite the care taken during its design.
• Not to be exhilarated by the success of a product, continue to work hard on a new product.

Life is made of successes and failures, it's the same here :)
