Quote by Bernard Baruch
Only as you do know yourself can your brain serve you as a sharp and efficient tool. Know your failings, passions, and prejudices so you can separate them from what you see. Know also when you actually have thought through to the nature of the thing with which you are dealing and when you are not thinking at all.
Summary
This quote highlights the importance of self-awareness in utilizing one's mind effectively. By truly knowing oneself, including one's limitations, biases, and personal inclinations, it becomes possible to distinguish personal perspectives from objective observations. Furthermore, understanding whether one has thoroughly contemplated the essence of a matter or simply lacks critical thinking allows for more rational decision-making. Ultimately, acknowledging and harnessing self-awareness empowers an individual to use their mind as a discerning tool.
