person A: I know I have high potential so the fact I failed my college course had me down.
person B: Well that's not good. I'm sorry to hear that. Do you think maybe you were just too nervous during the test?
person A: The test and the whole semester I just didn't give it my all like I should have and now I feel really crappy and regretful I need to redo course and give it my all.
person B: Never be too confident! You've got to give life your all at every step.
