Perseverance is reached also by when a person is independent and takes responsibility for him. Being optimistic and having self-confidence help to reach your goals and purposes. Think about what you can do, not what you can't do. It also helps to learn from your mistakes and the mistakes of others. I personally believe that a person should have a good role model who has a huge affect on someone's life in a positive way, a good role model having good characters like always striving for excellence and success. Don't quit. Success arrives for every person who perseveres and follows his dreams.
Have patience with all things, but mot importantly have patience with yourself. Don't lose courage in you negatives, but think about improving them. You have to find a way to accomplish a goal, or you have to make one. You have to wake up with determination if you want to go to sleep with satisfaction. I also think that when you start a task, it is always too soon to quit. Every little step gets you closer to where you're going. Don't turn back when you're almost done accomplishing a goal.
Perseverance is not a long race; it is many short races one after another. You might have to fight a battle more than once to win it. Big shots are little shots that keep shooting. Try and fail, but don't fail to try. Winners are losers who got up and gave it one more try.
