Success is a tricky word to pin down and define. It’s totally subjective to each individual, yet we tend to define others’ success by our own definition. And, just to make things more difficult, as you achieve success, you might redefine it so that you can work yet again toward the goal of achieving success (with its new definition).
At this moment in time, I define success in my writing as being able to make a living off my writing. I’m not there yet (not even by a long shot!), but I want to get there.
What about you? What is your (current) definition of success?
