Parents have a God-given power to give or take away confidence from their children.
How can you give confidence to your children?
Be supportive. Be always there for them, both in sunshine and in rain.
Highlight their strengths and talents.
Believe in them: in their innate goodness and in their ability to perform and get better in all areas.
Give unconditional love.
How can you take away confidence from your children?
Reject them when they make mistakes.
Give love only when they act as you like.
Tell them how bad and incapable they are.
Tell them how you are ashamed of them.
So, my dear parent, choice is yours. You can enhance or ruin your child's life.
