You've got to have a problem that you want to solve; a wrong that you want to right.

There are no problems, only solutions.

When you first start off trying to solve a problem, the first solutions you come up with are very complex, and most people stop there. But if you keep going, and live with the problem and peel more layers of the onion off, you can often times arrive at some very elegant and simple solutions.

If a user is having a problem, it's our problem.

Mankind always sets itself only such tasks as it can solve; since, looking at the matter more closely, we will always find that the task itself arises only when the material conditions necessary for its solution already exist or are at least in the process of formation.

Having no knowledge is sometimes exactly what is needed to find a solution, so I qualified.
