Do you think it would be possible to train another person to think higher of themselves?

Hello everyone, I have a kind of odd hypothetical question for all of you today.

I was wondering, would it be possible to train another person to think more highly of themselves. To have a higher self esteem and self worth, to feel more attractive, to be more confident and assertive.

Lets say for example, you have an employee who can’t refuse to do what you tell them, or someone who is just willing to go along with what you tell them to do. Someone who is willing to learn and listen to what you tell them.

If this person had low self esteem, and saw themselves as an under achiever, thought they looked ugly or average at best, and had no confidence, do you think it would be possible to use your power/influence over them, to make them think higher of themselves?

Would the very act of attempting to “impose” this feeling of high self esteem automatically make it impossible?

In other words, hypothetically, would it be possible to train/coach/force another person to think higher of themselves?

If so, how would you go about it?
