Input: Consider Input: Article: It's wonderful to go to another country, complete a volunteer project and feel that you really have a positive influence. But how can you become an international volunteer? * Plan practically. Contact the organization a few months before leaving and find out if there are materials which are rare and hard to attain for the project. What you often consider plentiful here, such as nails or hammers, is in great need in other parts of the world. * Do the project together, not on your own. You are a guest in the community. The most successful result is not that you build something and walk away, but that you and the community build something as a team. Share skills and build together. * Be flexible. Not everything is going to happen as planned. Often the other country doesn't have the right tools, manpower, transportation or funds to get all the needed work done. In a word, they lack infrastructure . * Contact with the people in the community. Often you will have "downtime" outside of the range of the project. Rather than retreat to the group with whom you traveled, be sure to spend time with the people of the community. Listen to the things about their lives. If you can't speak the language, smiles work wonders. And you will be surprised -- you will find a way to community. Volunteering is a special and life-long experience for everyone involved. Be prepared that the person who may be changed most is you. It's a joyful, often careful experience which will encourage you to view yourself, your neighbors and your world quite differently.
