Excerpt from my book "Awakening the Harmony Within" (the "Mind Mastery" chapter):

"Fully embodying the belief that we create our reality frees our consciousness range from self-imposed limitations. This is the first step of the path of Self-Mastery – the mastery of the Mind. We become aware that we are responsible not only for our actions, but also for every thought we have. We then recognize that we must become disciplined in tracking these thoughts to their conceptual origins, and facing head on our fears and misconceptions.

At first this process is much harder than the victim way of life, when we simply blame others, the world, or life for our problems. It is difficult and takes incredible vigilance to be able to pay attention to feelings and thoughts – all of them!
People who are more mentally inclined might find it easier to track the thoughts, while those more emotionally inclined would find tracking their feelings easier. But in the end the result is the same – it leads us to the origin of the belief (we can feel it, or know it, or remember the actual circumstance) so we can change it."
