Your mind will always have a tactical advantage because it knows everything about you. You can lie to the world but at the end of the day, the reflection in the mirror knows the truth. That’s why you should learn how to use it constructively. When you’re tired and feel like quitting, listen to that voice inside of your head saying, “You’ve got way more in the tank! Quitting is not an option.”
You have 2 choices:
1) Master your mind.
2) Allow your mind to be your master.
