“Not everything that can be 
counted counts, and not 
everything that counts 
can be counted”
Albert Einstein

"This is why I value that 
little phrase "I don't know" 
so highly. It's small, but 
it flies on mighty wings. 
It expands our lives to 
include the spaces within 
us as well as those outer 
expanses in which our 
tiny Earth hangs suspended."
Wislawa Szymborska
