You need to value time to move ahead in life. Punctuality is one such moral which every person should follow. After all, no teacher will like a child who comes late and no employer will like a late coming employee.
You might give numerous reasons for your late coming, but the fact remains that a person needs to respect and value time to understand its importance and to move ahead in life.
The best way to produce punctual adults is by teaching punctuality to children from their early days. You need to teach them to value time and to be punctual in every task they perform.
As a parent, you first need to ensure that your child reaches school on time. This implies having some fixed timings for him to sleep and wake up. Having some sort of discipline at home helps as it teaches the child the importance of time and punctuality.
Children learn more by watching and imitating their elders. Thus, along with teaching punctuality, you need to preach it. You need to be punctual yourself and your child will automatically learn and adopt this important value.
Additionally, you should reward your child when he is punctual and finishes his tasks on time. A reward does not necessarily mean monetary rewards; it can be simple words of encouragement too.
If you should reward and encourage your child for being punctual, you should also punish him if he refuses to follow the basic moral of punctuality. For example, if your child is not punctual, then you can punish him by canceling a fun trip which you had planned.
Whatever you do, you need to ensure that your child gets the message clear that punctuality is a value which is extremely important for moving ahead in life. After all, you need to make your child punctual so that he blossoms into a successful adult.
