Fear is your best friend or your worst enemy. It’s like fire. If you can control it, it can cook for you; it can heat your house.

In this quote, Mike Tyson compares fear to fire, showing that it is neither good nor bad by itself. Fear becomes beneficial when controlled and harmful when it controls us. Tyson encourages developing emotional discipline so fear can motivate better decisions rather than create panic. The message teaches that mastering emotions is a key part of success and personal growth.
