There are times that names of people reflect who they are, however there are many cases that it didn't.
And with regards to my name, Cathyrin, which means pure, well I could say that it reflects a bit but not that much.
We were given names at the point that we have no knowledge of anything for we are still babies. Our parents may have the meaning of our names in mind, which they want to reflect our personality when we grow up. Yet, it is not they who will decide who will we be in the future, it's us. So if we want to reflect our personality with our name meanings, then its always up to us.
