Question

write a letter to your friend who failed and to encourage him

Answer 1

Dear Mellow,
I know you are having a hard time accepting your result. I know you are extremely sad. However, remember that the world doesn't stop. You have to move on. Think of this failure as a trial, as a step to move forward and improve. Don't let this bring you down, don't drown in grief. Get up and work harder. I believe you will win next time.
Yours X
