Six things you can do to eliminate these obstacles and develop a Positive Mental Attitude:

1. Instead of worrying about who did what and who is to blame, focus on where you want to be and what you want to do. Get a clear mental image of your ideal successful future, and then take whatever action you can to begin moving in that direction.
2. Focus on the solution instead of wasting time rehashing and reflecting on the problem. Solutions are inherently positive, whereas problems are inherently negative. The instant that you begin thinking in terms of solutions, you become a positive and constructive human being.
3. Assume that something good is hidden within each difficulty or challenge. Dr. Norman Vincent Peale, a major proponent of positive thinking, once said, "Whenever God wants to give us a gift, he wraps it up in a problem." The bigger the gift you have coming, the bigger the problem you will receive. And if you look for the gift, you will always find it.
4. Assume that the situation you are facing at the moment is exactly the right situation you need to ultimately be successful. This situation has been sent to you to help you learn something, to help you become better, to help you expand and grow. One of the affirmations I have learned to use is this: "Every situation is a positive situation if I view it as an opportunity for growth and self-mastery." You cannot say that without thinking positive thoughts, feeling positive emotions, and seeing positive actions that you can take.
5. Assume that every setback contains a lesson that is essential for you to learn. Only when you learn this lesson will you be smart enough and wise enough to go on to achieve the big goals that you have set for yourself. If you are busy looking for the lesson, you cannot simultaneously think about the difficulty or the obstacle. And you will always find the lesson.
6. Whenever you have a goal that is unachieved, a difficulty that is unresolved, or a problem that is blocking you from getting where you want to go, sit down with a pen and piece of paper and make a list of every single thing that you could possibly do to resolve the situation. As you write, all kinds of insights and ideas will pop into your head.
A Positive Mental Attitude is indispensable to your success. And all it takes is for you to always take these six actions that are consistent with achieving your goals rather than actions that make you feel the negative emotions of worry, doubt, anger, and fear.
