PROBLEM: 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.
Answer: make good preparation in advance

SOLUTION: When you volunteer to join in a project, you are advised to _ .

PROBLEM: Article: Sitting in the play area of the doctor's office, my children, Paul, four, and Bailey, three, built a Lego tower while we waited to be called for Paul's examination. "Good job, you guys,"I said, trying not to sound too tired. My husband was away on business, and it was difficult being alone with the kids. At times I felt like I was living in the jungle rather than the suburbs. "Don't put the Lego in your mouth, Bailey,"I said. Paul grabbed it from him."That's not nice, Paul,"I said. He gave back the Lego. I looked around the waiting room. A woman was eating something, a couple were talking, and an old gentleman in a blue jacket was reading a magazine. I wished I could sit quietly for a while. I wanted to be able to take a rest, or go shopping alone. At once, I was ashamed of myself. What kind of mother was I? "God,"I thought, "help me to be the very best mom I can be." The nurse came into the waiting room to get us. Just at that moment, the old gentleman in the waiting room put down his magazine and came up to me. With a smile on his face, he said, "Your children are most certainly lucky to have such a wonderful mother.""Thank you,"I replied in a low voice and watched him walk back to his seat. We followed the nurse into the examination room. While she weighed Paul, I told her how that man had made my day. Motherhood is still a jungle sometimes, but now when I feel tired I remember the encouraging words of the old gentleman.
