Invest in helping people to discover the powers within. Do not invest in making people think they need to depend on some external rich power to pull themselves out of their misery. That is misservice. This is lie. That warm, fuzzy feeling you get after spending billion on buying stuff for poor people comes with deeper unease - deep inside you know that you did not really make a lasting difference. Difference yes. Lasting - only until that billion ran out and your vaccines are used, food is eaten and very soon they will want more. This is not a difference.
Invest in helping people to learn the skills, invest in helping people to find inspiration within, invest in helping people to express their own creativity and power.
Invest in helping people to discover how each of them can help other million people without spending billion dollars.
