What is the best contribution to humanity you have?

This isn’t the same as what you think your best talent is. Rather, this is what you think your best talent is that the rest of humanity could benefit from, in their opinion. If you were really going to help the rest of us out, what would you be doing?

Is this the same as what you do now? Do you enjoy doing this? What do you wish people would see as your best contribution, if it is different from what you think they want? How do you explain the difference between what you think is your best thing and what other people think is your best thing?
