When do parents cross the line between healthy encouragement to prepare their children for success and pushing them to succeed at all costs?

Well one is they are supporting the child in his/her choices in the field of what they chose and doing what is in their power to help said child.

The other is making them try to be number one and doesn't care about what they really want to do(usually) and try to do what's in their power to make them win. Usually the feeling comes when the parent/s has something in their past that they didn't succeed so they force their child to live the life they had as kids, but to give them what they got to win in life or in that area.
