For example, if you love your neighborhood, support local businesses. If you love the Earth, recycle and compost. When you travel, look into staying at hotels and participating in activities that are both eco and socially aligned. Those are easy choices that help you feel (and be!) aligned with your values.

Your next step after a fall: Brush yourself off and examine what happened and why, then continue on the path with this new knowledge. Each time, it gets a little easier.
Every choice we make makes a difference.
