How to get people to do what you want

Encourage, praise!
There is nothing more that diminishes a person wish to serve you well than critism and disdain.
"I have yet t ofind the man,however great or exalted his position, who did not do better work and put forth greater effort under a spirit of approval than he would ever do under a spirit of criticism"
Harry Schwab-- who was paid a million dollars a year in the 1930's!

How to make someone feel important

"If you want to gather honey- don't kick over the beehive"
That is it.
Basically- do not critize whatever or whoever you are trying to get a point of influence from. It puts people on the defensive and make them strive to justify themselves.
Critism is dangerous it wounds pride, hurt peoples sense of importance and aroused resentment.
Do not kick the beehive!
