If you want to be happier, exercising and eating better are two great ways to start. However, if you want to be happier, the combination of helping people, learning new things and meeting new people makes volunteering a winning choice. If you're unsure how to start with volunteering, list your passions, interests and hobbies. Then, do a search for local businesses and organizations related to them. Search their websites or contact them for volunteer opportunities--and before long, you may be smiling more.
