Sorry but that's a pretty outlandish statement. dogs may occasionally act like people, and they may require management, but they are not people. It doesn't follow that if you can't/haven't managed dogs you have no hope with people. I've done both and it's a different ball game.
Seriously? If you try to control people pain and reward system, most people see through it and hate you for it.
You want them to have a innate feeling of accomplishment. You completed something difficult? And that felt good. You don't need cookies from a master for that.
The number one thing you need to do, is set something up which they can measure themselves against. 90% of the time people will enjoy improving it, without any input.
The world isn't full of self-involved creatives who just want to create to create. Most people like being rewarded (money), promoted (power), and growing in their positions (knowledge).
