I am old -- so I am just sharing from my experience. There used to be a day when a child/teenager/adult would do their best and be satisfied with that.
The question is asked if too much self-esteem is a problem for American kids, and I think yes -- you bet. And here's why.
A child shouldn't have to be praised for doing what's expected. A child indeed however should be praised for things they give their "all" too and work very hard at -- great grades, competing in sports, working hard in their community etc... They shouldn't need to be praised for taking out the garbage, or making their beds, especially when family participation is expected.
Do we all like to be validated and patted on the back. Yes, and I am all for that -- but I really think that praising for every little accomplishment is indeed harmful. Kids need to learn about rejection, consequences and choices. If they don't how are they ever going to survive in this big world of ours?
We aren't going to be there forever wiping their bottoms and cutting up their food. You know what I mean?
