A couple great quotes

What information consumes is rather obvious: it consumes the attention of its recipients.  Hence, a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.     ---Herbert Simon, recipient of Nobel Memorial Prize in Economics and the A.M. Turing Award, the "Nobel Prize of Computer Science"

There are many things of which a wise man might wish to be ignorant. ---  Ralph Waldo Emerson (1803-1882)
