One of the most important things you can ever understand is that YOU ARE NOT YOUR MIND. You are much bigger & greater than your mind alone. Your mind is just a part of you just as your hand is apart of you.
Here's a thought-provoking question: What if you had a hand that was just like your mind? It was scattered all over the place, it was always beating you up, & it never shut up. What would you do with it? Most people answer something like"cut off!" But your hand is powerful tool, so why would you cut it off!? The real answer of course is you'd want to control it, manage it & train it to work for you instead of against you.
Training and managing your own mind is the most important skill you could ever own, in terms of both happiness and success.
