The Right Kind of Stubborn

How do I know if I’m being patient (a skill) or stubborn (a flaw)? They’re hard to tell apart without hindsight.

I’m thinking about how many people were one or two iterations away from the right formula, but lacked the conviction to stay the course, the understanding that minor, subtle, successive changes can drastically influence outcome. I’m thinking about how self-doubt makes more people abandon a vision than competition or lack of funding ever will.
