What is your teen good at
Thinking about this may help your teen find something about school they can really enjoy.
If your teen hates reading and would rather do household chores than write an English essay, please dont force them to like it. Of course its important that they try their best in every subject, but sometimes youve got to call a spade a spade, and accept that your teen is never going to like every subject.
Whats far more likely to see your teen succeed down the track, is if you encourage them to pursue the subjects that they do enjoy. There are successful people in every industry. Your teen doesnt need to be a doctor or a lawyer to have a good career. If they have a subject that they like and enjoy, thats the thing they should really go for.
