If you believe that you cannot do something, then you won’t be able to do it. You won’t even start. If you believe you can, you might start.
Then you will meet an obstacle which tests the strength of your resolve. Resolve is a spiritual element belonging to your soul. When you begin to work with your soul and allow it to youse your mind – your ego – as a tool, then you’ll begin to live your life.
Your life; as in your soul’s life, and not your ego’s life.
