Having hope will help you expect a positive outcome.
One thing I've learned in life is to hope for our future in spite of the past. When I say "hope" for the future, I mean anticipate a positive outcome. It’s not about what challenges stand in the way or what circumstances you may have but more about how you can over come them to see a better future.
You are a product of your decisions not your current situation. What that means is no matter what happens you still have the ability to make tomorrow better than yesterday and everyday after that.
What you can do is see a reason to have hope and believe that you can and you will.
