A great achievement doesn't have to change the world. It doesn't have to be noticed by anyone at all. It could actually be shunned by society as a whole.
A great achievement is something that makes you proud, something that pushes you to the limits of what you can do.

There is one issue with defining a great achievement as such, however. People do *not* have limits when it comes to achieving.

A question to you all, what do you suppose a "great achievement" is, and do you feel you've ever do one?
