What is the connection of our thinking to our doing?
If someone feeds his mind with negative thoughts of worries, fear, anxiety and confusion, his life becomes one of frustration, fear anxiety and worry.
On the other hand, if another person feeds his mind with positive thoughts of a better tomorrow, good and worthwhile goals and work towards them, it will become a reality, because that is what he thinks about. If you keep feeding your mind with negative thoughts you achieve negative results.
