I don't have the DVD with me now, but in one of the bonus scenes of the film Helvetica, Erik Spiekermann, a German design titan, talks about how his satisfaction comes from the fact that he designed the signage of train stations that people rely on and pass by everyday without realizing the design was his work.
It's an interesting way of seeing things that I find, again and again, in people who design. It doesn't have to be visual design or typography: Think about designing a system, a software framework, a house, a mechanism, things that other parts rely on and people use.
To stretch a bit, hence: There are at least two kinds of people. One boasts how they are going to make the change. The other makes the change, and moves on.
