One thing that travel has taught me is that we often find time/money for the things we truly value or want. The poorest people who live with dirt floors and tin roofs often have a very nice T.V. because it's something they wanted.
If a life-changing experience is something you would find value in, then there is a way to make it happen, either through working or fundraising. If you are interested, Mr. Denning would be happy to help you brainstorm some ideas.
