There is…a voice inside me that urges caution. It tells me to be careful, to keep my head, not to go too far, not to burn my boats… I don’t want to be carried away into any resolution which I shall afterwards regret, for I know I shall be feeling quite different after breakfast… This is my endlessly recurrent temptation: to go down to that Sea [which is God], and there neither to dive nor swim nor float, but only to dabble and splash, careful not to get out of my depth, and holding on to the lifeline which connects me with my things temporal… Of course, that lifeline is really a death line.
~ C. S. Lewis
