If you want to be a volunteer, you have to answer the following typical questions. Do you want to work with people, animals or machines? Do you want to work indoors or outdoors, directly serve people in need or serve people behind the scenes? Every year, thousands of people in the west offer volunteer service. Volunteering greatly strengthens the community because it helps the old, the young, the weak, the sick, and the disabled and the injured to solve problems.

Volunteers usually help in many different ways. They may give people advice, offer friendship to the young, drive the elderly to church (if up to the driving age), advise kids against drugs, work as assistants in schools or nursing homes, raise funds, plant trees, help out in local libraries and do many other things. Volunteering can be a few hours a week or a few hours a month. Anybody who wants to serve people in need can become a volunteer.

In fact, the art of volunteering is a process of both giving and receiving. Volunteering allows volunteers to meet new people, make new friends and mix with people from all walks of life. Volunteering is an excellent way to experiment and try out new techniques and skills, discover your individual talents and explore career choice. Being a volunteer will take you on a wonderful journey and help you learn more than what you can get from books.
