Remember, it is not situations that defeat you. Situations are just situations. A situation by definition is something outside of you, whereas defeat is something inside of you.
Situations can at worst be adverse, correct? And a situation is always external. The sense of defeat is an internal thing; that should not come to you.
There is nobody who is not going to face adversities or reverses. It is your response to those moments that will decide your fate. In victory everybody is a champion. You must be a champion even in defeat. That’s what is needed.
