"He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast"

This quote by Leonardo da Vinci is a warning against doing something about it without taking into consideration the consequences. It is a pointer that without a strategy or instructions, it is impossible to understand where one is going or how to get there. The sailor in the quote is an allegory for somebody that does something about it without thinking about the repercussions. Without a rudder and also compass, the seafarer has no way of recognizing where he is going and also is likely to wind up shed and also adrift. In a similar way, a person that enjoys technique without theory is most likely to take action without considering the consequences as well as will certainly never recognize where they may end up. This quote is a suggestion to constantly think about the consequences of our actions as well as to plan ahead before acting.
