Volunteering can be beneficial in many ways. It can help you feel you are contributing to your local community.
It can help you get a feel for the kind of work you might want to do in the future. It can help you stand out from the crowd when applying for Colleges or University. It also gives you the opportunity to show and develop a range of employability skills such as commitment, dedication and enthusiasm.
So in addition to helping others, volunteering may be a way of helping yourself. Gaining retail experience in a High Street Charity shop may be a way of helping you get a part time job to financially help you through University for example.
