Persistence is the key to success, whether for a single person or an organization. The lack of it would mean failure in reaching a certain goal.
Success seldom comes easily on the first try. What separates the successful from the unsuccessful is persistence. Successful people also fail from time to time, but they don't let their failure defeat their spirit. Successful people learn from defeats, revise their strategy as needed and try again and again until they succeed. Unsuccessful people try something once or twice and when it fails, they give up, usually passing the blame on to someone or something else, and learn nothing from their own experience.
Successful people expect periodic defeats, learn what went wrong and why, don't waste looking for someone to blame, make necessary adjustments, and try again. If you are persistent, you will almost inevitably succeed. If you are not persistent, you will almost certainly fail.
