What made me decided to become a designer was after several semesters of taking a ceramics class. I really enjoyed creating something out of nothing and working clay really pointed that out to me. It wasn't until after a conversation with my ceramics teacher, that I decided to pursue a degree in Industrial Design.
It is hard to say. I usually do a large amount of sketching to find a general direction or idea. Then refine, refine, refine until I have a solid enough idea of what it will look like and then bring into a CAD program. But that is suggesting that all of that goes to plan, which sometimes is not the case.
I think that a design is successful when it looks as though it hasn't been designed at all. When there has been so much thought involved in creating it, that when someone sees it for the first time can't find anything wrong with it.
