Positive emotions broaden your mindset and open you to consider alternatives when trying to solve a problem, as well as you build social relationships.

That statement is true

By having positive emotions to observe your problems, you would not see the problems as mountains that you can never be surpass but as a challenge that you need to defeat in order for you to develop and become a better person. So your mind would constantly seek new ways to improve your life and bring positive benefit for the people that came across you.
