Great design is serious (not solemn): A reaction

In class, we were shown this talk by famous designer and partner at Pentagram, an equally famous client design firm, Paula Scher. The basic premise is that the designer's life is composed of quick growth and punctuated by growing plateaus of mediocrity into oblivion. Kind of a downer. She goes on to say that this can only be combated by attempting things you know nothing about, even then, eventually you begin to draw your own conclusion and the cycle starts again.

It made me think of my own art, there were strong parallels to what she described and what I am going through as an artist. I can honestly say I'm a "better" (being a relative term) than I was when I started. Which each new drawing I learn something new, I used to search volumes of books searching for answers, now I stumble over them. Even though I don't see the plateau, I'm not satisfied and there's a lot I don't know and can't do, but I fear that Ms.Scher was right. What if one day the well dries up?

I remember the words of a teacher whom I respect, "analyzation is paralyzation". I think I butchered the actual words, but the thought helps.
