How can Mind Power help us to achieve goals? Quite simply, we tend to get what we focus on. If anything in this life is achievable then by directing Mind Power it can be achieved. But first we have to BELIEVE that we can achieve.
If I want to do something and I tell myself I can't do it, then I will fail. Unless, by a small chance something miraculous happens to put my goal in my path. And even then, I may fail if I don't believe I can succeed.
But when I tell myself, 'yes I CAN do this' - 'it is a certainty that I can SUCCEED' - then I am already half way up the mountain. The summit will be reached by work and determination but knowing it can be reached makes that journey easy and enjoyable.
