The human brain is a tenacious creature of habit, and by repeatedly thinking the same thoughts or mentally expressing the same judgment, we can begin to form permanent patterns of belief in just a few hours. As Ralph Waldo Trine points out in Character-Building Thought Power, these processes occur whether we are conscious of them or not, so it is in our best interest to try to direct these patterns to work for us, rather than against us. Trine offers a series of easy-to-implement suggestions to help readers put the power of thought to work in their lives.
