Positive is to be assured, and make a good contribution.
Think of the things you can do to take positive actions. Perhaps you could choose a community service project to do. Whether it involves cultivating a school garden, participating in recycling efforts, or contributing cans for a food drive, all of us can benefit from the feelings of competence and confidence we get from engaging in a service project.
We all hear about positive actions, but we need to give ourselves the chance to practice them.
