“ A man is not idle because he is absorbed in thought. There is visible labor and there is invisible labor. ”
Source: Les Misérables
We often miss opportunity because it's dressed in overalls and looks like work
Man suffers only because he takes seriously what the gods made for fun.
Ignorance is servitude, because as a man thinks, so he is; a man who does not think for himself and allows himself to be guided by the thought of another is like the beast led by a halter.
