Understand that everyone here on Earth is learning just as you are

You could be a smart student who got a bad test score because you didn't study but in the eyes of a grader, it doesn't matter what your excuse is. What matters is your results.

No matter what age you are, or what your circumstances might be, you are special, and you still have something unique to offer. Your life, because of who you are, has meaning. Just because you are seventy is no excuse to give up and let others make your decisions for you. The fact that you are still alive is the reason enough to believe that you are here for a purpose; and that purpose is to learn, to teach and to give. The are two things to aim at in life; first to get what you want, and after to enjoy it. Only the wisest of Mankind has achieved the second.
