Is the idea you can do anything good?

The idea that anything can be achievable if they make enough effort could be widely heard by parents in some cultures. I would like to discuss the positive and negative infuluence for children. The advantage would be that we can encourage kids to draw a big dream and work hard toward it. In deed, I personaly believe every children have unlimited potentials in every aspect. It is important for parents or teachers not to limit thier future possibilies and options. On the other hand, I would like to point out the importance to tell them that everyone has the different situation and every human beings has the unique body and talent. For example, if your kid was born as Asian appearance and wants to become White look, it is impossible and should not encourage to dream it. In that sense, “anything” could be sometmes incorrect. Adults should always watch out thier goals are appropriate.
