Always praise your kid even if he/she is unresponsive to learning. By insulting them and putting them down, you will only push them away and make them feel inadequate around other kids. Have faith that your child's brain is an evolving planet that rotates at its own speed. It will naturally be attracted to or repel certain subjects. Be patient. Just as there are ugly ducklings that turn into swans, there are rebellious kids that turn into serious innovators and hardcore intellectuals.
