There numerous slogans do describe how the knowledge defines various aspects of our lifes.
I like this simply genius one – equation by Albert Einstein:
Ego = 1 / Knowledge
"More the knowledge lesser the ego, lesser the knowledge more the ego."
I glued this idea on two sides of the cup; so both of us would be reminded that knowledge gives us understanding; understanding creates skills; skills bring opportunities; opportunities extend freedom, freedom makes us lean more, and knowledge reduces our ego.
