The only validation I need is that whenever I visit parts of Mumbai, there are kids who know that 'singapore didi' will find a way to help them pay for school. 2800 kids now, but I stopped counting. Scaling prematurely and seeing the macro picture works for some people / orgs but I feel it misses out on the individuals in question. I know the stories of the people the org has helped. I know their families. That matters to me.
