Before moving to New York City, I lived in San Francisco. There one morning, my yoga teacher talked about why he practices yoga every morning. He called it the "art of sequencing." In essence, by making healthy choices first thing everyday, you boost your feeling of wellness. In turn, you'll be gentler on yourself and others. This in turn generates a sense of happiness that will also help you make better decisions as the day progresses. Then, by the time you climb into bed at night, you'll be tired, but peaceful and happy.
This doesn't mean you have to wake up and tie yourself in a knot. It doesn't even mean you have to do yoga. Whether it's eating a healthy breakfast, rocking out to some tunes while getting ready for work, or putting on a nice outfit, any small healthy decision can boost your confidence and overall outlook on life.
