In a chat with a friend we were talking about Connor McGregor's mindset (he was/is a UFC fighter and a multiple champions) I think he is one of the most vocal when it comes to the power of your mind.
I have watched hours of his videos. It's worth watching and learning.
In this video Connor talked to Tony Robbins about mindset and worth the listen.
Here's a POWERFUL quote from this talk:
Your lack of commitment is an insult to those who believe in you.
馃槻 WOW.
