Optimism and health? Fact or fiction?

I believe that is very true, but also other factors are involved...are we wallowing in guilt or pity..do we grieve over lost loved ones...how about decisions in our life we have made and chose not to make the right choice...we can see the positive or negative in any situation..the secret is learning to let go...the mistakes, the burdens, the regrets..we have to trust that God is in control and He knows which road we should take..Just let go and learn to be happy..no matter the outcome...
