Your perspective on a situation can either give you life or death. 
It's not about looking at something with with ignorant optimism, but acknowledging what is right in front of you and choosing a perspective that will serve you, not take from you. 
In this podcast I discuss a little more in depth what it was like losing our daughter at almost 7 months pregnant, almost losing my life while delivering her, and how I came out of what felt like one traumatic event after another better, stronger, and more confident that God is good than ever. 
I hope this encourages your spirit but also challenges you to look at your perspective and take control over it so you can live your best life.
