In the end, we'll come to terms with our shortcomings, with our successes and with our failures.
To put things in perspective, sometimes we blow things out of proportion, we place too much emphasis on one thing and fail to see its insignificance in the grander scheme of things.
Sure, it may be important, but that doesn't mean that its the end.
Life has many turns - it's up to you to see the brighter side. In the 70 - 90 years of your life, at the end, it might not matter whether you got an A or whether you became a successful accountant.
The thing I'm trying to drive at is that: just do your best. Sometimes, yes, it may not be enough. But then again, what can you do about it. Just move on. Try again.
Smile, even though it's hard. Because being positive will make things easier. Everyone is going through the same shit, but it's up to you to survive on your own. So smile. Make yourself happy. Don't base it on others.
