Robert Greene said this quote
“ Understanding the world too well, you see too many options and become as indecisive as Hamlet.No matter how far we progress, we remain part animal, and it is the animal in us that fires our strategies, gives them life, animates us to fight. Without the desire to fight, without a capacity for the violence war churns up, we cannot deal with danger.The prudent Odysseus types are comfortable with both sides of their nature. They plan ahead as best they can, see far and wide, but when it comes time to move ahead, they move. Knowing how to control your emotions means not repressing them completely but using them to their best effect. ”
