When working on a community project depending on what it may be, you may learn more about its special history. You can learn about the community itself, and maybe about yourself and discover a hidden talent you didn't know you had. It is also suppose to be good for you. It reduces stress, as your mind will be focused on something else other than what's going on in your private life or at home maybe. Community work also brings people together. It unites people from diverse backgrounds to work towards a common goal, it also builds up teamwork and co-operation. You also would make a difference, because every person counts!
