Well said my friend @humanearl. I really like how you are regaining your health.
We already know that what you focus on you attract. Worry, fear, and negative thinking allow the mind to focus on things you don’t want, so Mind Power teaches you to eliminate negative thinking. Train your mind to think about what you want in life, and avoid thinking about what you don’t want. Negative thinking drains your energy and is counterproductive; that is why fear is so destructive and why despair and hopelessness must be avoided. They work in the opposite way that Mind Power does.
A thought has no power other than what you give it. Negative thoughts gain momentum when you think them over and over again. So stop thinking them.

The key is to catch the negatives before they have time to become entrenched. With practice you will notice right away when you are thinking negatives, and you then can take the appropriate actions. The mind is a creature of habit, so encourage positive thoughts and eliminate negative ones. Really excited about your well-being now.
