I will go far enough out on the limb to say most people have this desire, manifesting in some way or another. This is why I don't rush out to learn to write romance novels. I wouldn't read one if I'd written it. And that would make editing difficult. I agree entirely that improvement is life.
Stagnation is death.
On the other hand, not all motion is desirable motion. By this I have arrived at this set of ideas. First, that I should try whatever appeals to me. Failure is solely defined as not doing this. If I create, and I don't like it, I have succeeded in narrowing the field for my work.
