Everyone wants to be happy, but the biggest obstacle to that is the mushy thing inside your skull that you think with.
The brain is designed to put more weight on negative thoughts than on positive ones. This imbalance takes us away from experiencing positive emotions such as joy, gratitude or hope.
Having positive emotions helps us become relaxed, playful and learn new skills more easily.
However, it is important to have a certain amount of negative emotions to be able to be creative and resilient.
