This is the complete Serenity Prayer by Reinhold Niebuhr

God grant me the serenity to accept the

things I cannot change,

Courage to accept things I can change, and

Wisdom to know the difference.

Living one day at a time,

Enjoying one moment at a time,

Accepting hardships as a pathway to peace;

Taking, as He did, this sinful world as it is;

not as I would have it;

Trusting that He would make all things right;

if I surrender to His will,

That I may be reasonably happy in this life,

and extremely happy with Him forever in the next.

Amen.

"Courage doesn't always roar. Sometimes courage is the quiet voice at the end of the day saying, 'I will try again tomorrow'."
