Be bigger think rather than the disappointments. Feel your internal voice, understand them, learn from them, and then move forward from them.
Many things can get you down. Nothing has to keep you down.
As difficult as life can be, you can be positive about it. Choose a positive perspective, positive thinking, positive words, positive actions, positive expectations. this behaviour changs all circumstances time to time. but you have to patience.
In any situation, there is a way to respond that makes the situation better. There is a way to create value.
The troubles can often be big, yet you can be bigger. Seize the opportunity to build strength, capability, experience.
Experience each disappointment precisely once, refusing to let it echo through your life. Take the energy and turn it toward something good, useful, positive and fulfilling.
