"I see now, working in the humanitarian world, we start to help people, and we get derailed by conflict of ego, corruption — human shortcomings. So the best thing you could do instead of training to run an NGO or make accounts would be to start to become a better human being so that you can serve others better and not be distracted by trying to make everyone perfect on the way. That’s the job of the Buddha, not your job."
