Help me to go to Africa as a teacher!

I`m planning to go to Africa as a volunteer. A lot of schools there need in helping of teachers, doctors and etc. Everybody has the right to have good education. Unfortunately, they have less chance of having higher education but we can help them if we unite for children.

This idea came to me two years ago when I had read memoirs of Audrey Hepburn. It`s extremely important somebody makes others do charity and volunteer work and I hope to give a great example for my acquaintance.
