  The Unknown

 As we know,
There are known knowns.
There are things we know we know.
We also know
There are known unknowns.
That is to say
We know there are some things
We do not know.
But there are also unknown unknowns,
The ones we don't know
We don't know.

In short: There are some things we know about this world for sure, and then there are some things which we know we don't know and then again! there are things we don't know that we don't know. And frankly, discovering the things which we don't know we didn't know is what keeps life exciting.

For example, until I came to US the second time and discovered personal finance blogs like The Simple Dollar, I never knew there is a serious Financial Planning aspect to life (and for now I am hooked to it :)).

Joy of discovering new things in life or (or web for me) is what keeps life exciting.

Happy Discovering!
