Your worst habit and your best quality are often one trait in two outfits. Stubborn also finishes things.

Most of what gets called a flaw is a strength pointed the wrong way. The friend who will not drop an argument is the same person who will not drop a project three weeks in. Traits are not good or bad on their own; they take their character from where you aim them.

Take the thing you get criticized for most and ask where it has helped you. If people call you too intense, find the place that needs intensity, like a tryout or a deadline. Then watch for the hours when the same trait is costing you, and spend it somewhere better.
