The barrier to change is not too little caring; it is too much complexity.

To turn caring into action, we need to see a problem, see a solution, and see the impact. But complexity blocks all three steps.

If we can really see a problem, which is the first step, we come to the second step: cutting through the complexity to find a solution.

Cutting through complexity to find a solution runs through four predictable stages: determine a goal, find the highest-leverage approach, discover the ideal technology for that approach, and in the meantime, make the smartest application of the technology that you already have — whether it's something sophisticated, like a drug, or something simpler, like a bednet.

The final step – after seeing the problem and finding an approach – is to measure the impact of your work and share your successes and failures so that others learn from your efforts.

But if you want to inspire people to participate, you have to show more than numbers; you have to convey the human impact of the work – so people can feel what saving a life means to the families affected.
