The first and foremost way to motivate kids to achieve their goals is to encourage them to set up short-term targets that are both fun and engaging and will prepare them for long-term ones. This can be done through a thorough discussion, sharing inputs and a well-written plan. Parents can also include them in their goal achieving process from time to time.
The best way to prepare a proper plan is to set goals that are attainable, deciding on an action plan to achieve it and finally keeping track of the progress. If a child fails to accomplish their set targets, parents should sit with them, assess the difficulty levels, revise them if needed and encourage them to look for new ideas and to do better the next time.
