If you want to help someone then you'll need to 'Provide skills, not just finished technologies'. There is an old saying "Give a man a fish, and you feed him for a day. Teach a man to fish, and you feed him for life." I think that is how we can save the world. In 2020 when I'll be 31 years old, I will be in the heart of Africa and help people understand that if they want to move forward they need to understand what skills they need. Also by making everything as simple as we can, then everybody will understand what is the solution and put it in practice. This can be achieved throw stories. Tell them tales and stories and not just facts. It is important not to fight the culture. Make everything like an adventure and at the end of the day they will find the ultimate solution for their problems.
