Help me plan a trip to change lives. Any input welcome and needed!

I am currently 19 and want to use my life to help others within the next few years.

I really have no idea where to start, it’s just something I really want and feel that I need to do.

My idea right now is to ride around parts of ******* (help me decide where I could help the most) on a strong bike with a custom trailer made of solar panels and mini wind turbines. Maybe the trailer could have a screen/projector mounted with short films from around the world playing of people just waving to let the people know others are thinking of them and pictures taken from space stations/other locations to make them aware of the earth, because they deserve to know.

Maybe a satellite phone with a list of peoples numbers to phone (maybe you guys) so they can experience Talking to people on the other side of the earth.

Along with medical care, water purification tablets, education, general assistance in building, toys, and any other ideas!

My questions are many and all... Is it possible, how, where, who, what. Literally ANYTHING! This is a blank slate for us to write on.

Thank you 
