"Nobody can give you wiser advice than yourself." 
-Cicero

"The reason that ego and love are not compatible comes down to this: you cannot take your ego into the unknown, where love wants to lead. If you follow love, your life will become uncertain, and the ego craves certainty." 
-Deepak Chopra

"Uncertainty is the only certainty there is, and knowing how to live with insecurity is the only security"
-John Allen Paulos
