Believe me you will know. Simpler living is a personal process. Go at your own pace. We all backslide because old habits die hard. Set your own standards and be gentle with yourself.
Simpler living can mean different things to different people.
For some, it could mean a career change, going back to nature, getting rid of clutter, or making room in their lives for what is important. Nevertheless, at its core, simpler living is about balance. I'm not comfortable with visualization, affirmations, meditation, etc. Meditation, visualization, and affirmations are simply tools for focusing your mind. As long as you understand the principles of these tools and incorporate similar techniques, you will be able to achieve peace of mind.
