When you tell me that...

Our professor said that we need to write something about "When you tell me that..."
This is what I have come up so far. Specific instructions were 3 paragraphs and 7 sentences per paragraph. But I am all out of ideas. Please help. The scope of subject is not specific so any would do.

When you tell me that I am wrong, I will be grateful because in my mistakes I would use it as a goal to be better. I understand that no one is perfect that's why it is ok to make mistakes and to correct them. Mistakes are a part of being human. "Appreciate your mistakes for what they are: precious life lessons that can only be learned the hard way. Unless it's a fatal mistake, in which, at least, others can learn from." We shouldn't brood over the past instead we should cherish the present and think about our future.
