While your intentions are honorable and meant to help, the reality is much different. You in fact hurt your child by robbing them of necessary lessons in life about character, personal satisfaction, closure, self-discipline, and the iron will necessary to finish a job once started which in the beginning seemed overwhelming. Parenting and teaching takes not only sacrifice and energy, but also consistency. Good parents and teachers don't just happen by accident. People plan to be good parents and teachers and good parents and teachers plan.
Good planning requires consistency.
I'm always delighted when someone lists the goal of happiness for his or her children. However, I am concerned when parents emphasize that they want their child to become a doctor, lawyer, accountant, politician or some other profession. While I'm not questioning the worthiness of these professions, I am questioning the priority of the parents thinking. Thinking such as this is equivalent to putting the cart in front of the horse. The primary goal of the parent and teacher should be to build into the child's life the concepts, philosophy, and spiritual principles that will enable him or her to make decisions about their future.
