Try your best and leave the rest to God. I always say this to encourage myself because in life there are certain things you just don't have control over.
"The reason people find it so hard to be happy is that they always see the past better than it was, the present worse than it is, and the future less resolved than it will be."– Marcel Pagnol
Morality is one of the hardest things we deal with. It’s very rarely black and white, and the conviction we have in any choice we make is only as strong as the beliefs we hold that drive them.
Believe in yourself, and the rest will fall into place. Have faith in your own abilities, work hard, and there is nothing you cannot accomplish." - Brad Henry
