A volunteer is “a person who freely offers to take part in an enterprise or undertake a task.” (Google, n.d.)
The joys of volunteering include doing good work, helping and serving others, meeting very nice and great people with whom you can become friends with and if they have the information they can pass across to you.
What is the purpose? To be helpful, make others happy, give joy and more light.
Do good work today and let your life be a blessing to others.
God bless you.
