Discouraged again?

Are you discouraged again?
Why are you discouraged again?
When you were discouraged,
I asked you not to be discouraged;
I told you the best was coming;
And you promised me
You would not be discouraged again;
What has happened?
Know it once and for all, sweet friend;
Life is not easy;
So you have to keep going
Even when the going is tough;
Stop giving in to discouragement.
