Do not let your child fend for themself in this world. Yes, a child can be smart but a child can often lack common sense like I did.
I have made a list of things your child needs to know.
Teach a child:

Cooking is a forever skill. A child should not have to rely on McDonald's for their meals. We all need to eat. You should teach a child how to prepare healthy and frugal meals. Expensive meals are not always the healthiest.
Give your child a chore. Reward them for this chore. Make them feel important.
Child obesity is rising. Turn on YouTube and search for an exercise video.

For example, give them some crayons and gel pens with some coloring books and let them create masterpieces!
Often, it is the parent that needs to be taught how to behave. So many parents use foul language and they usually say such language in front of their kids. Then, the kids pick up on this language.
For example, around Christmas, let them choose a gift to give to an organization.
Teach them to be frugal. Teach them to wear thrift store clothing, off-brand products, groceries that are on sale or clearance, dollar store toiletries, etc.
Finally, I am not criticizing you as a parent. Your child could be crying for these productive moments with you, yet do not know how to tell you.
I had to wait until I had grown up. Don't wait!
