Every one of us makes countless choices every day. Every choice we make has an impact on our lives.小题1:When hunger strikes, we con reach for a healthy, nutritious snack, or we can choose the* Sugar high of junk food. The more important the decision,

the greater its effect. For instance, how do I act towards that person who treated me badly? Do I generally choose to be passive, or do I actively set clear intentions and create what I want in my life? Every choice we make, however big or :<mall, affects us in some way.
