Be capable of persistently pursuing the goals you set.
Persistence is the ability to continue to act accordingly, even when you must deal with conflict. It is difficult to be effective and achieve your own goals avoiding responsibility for completed tasks, hiding important information and violating the agreed work terms because of the fear of expressing your displeasure or anger openly.
We allow and welcome honesty. Everyone has the right to speak out if something is upsetting in his/her endeavors. Honesty and openness will help to interact with business partners or colleagues more productively, reach a compromise quickly and find the best solution for tackling any issue.
