Good advice that I have learned over time is if your change your thinking, you will change your life. It is good advice because your thoughts define your life.
To grow spiritually in a world defined by power, money, and influence is a Herculean task. Modern conveniences such as electronic equipments, gadgets, and tools as well as entertainment through television, magazines, and the web have predisposed us to confine our attention mostly to physical needs and wants. As a result, our concepts of self-worth and self-meaning are muddled, and our outlook on the world becomes distorted. How can we strike a balance between the material and spiritual aspects of our lives?
To grow spiritually is to look inward, and to change your thinking. You must learn to control your thoughts to affect your outlook on life.
