Hi everyone. I am glad that you guys responded to my post. To clear some points out, I have been doing this to my sister because I want to reward her for he achievements. It somewhat a psychology thing; positive reinforcement (rewards) strengthens good behavior while negative reinforcement (punishments) weakens it. In this way, I can make her focus on gaining more achievements and doing the best that she can to achieve a goal. This strategy actually helped her to be more goal-oriented than she was before. However, it had resulted to an unwanted behavior. She has somehow see me as her reward machine or probably her wish factory. Due to this, I have decided to heed your advice that I should I can still pamper her for her achievements but still have to control her desire for expensive things since I want to grow up knowing there thing that she has to work for herself. Anyway, thank you so much.
