I have a 17 year old and a 14 year old, both boys.
I broke this down into very simple terms from a much younger age but it translates to pretty much every situation. I get what I want means you get what you want.
I want to take you shoe shopping because you need new school shoes, I expect and want you to be compliant, polite, and well behaved, if I get this then you get X whatever X may be, that is gaming, tv, etc.
So now it would be, you stick to the chore list, which they do, so unpacking the dishwasher, helping to make lunch if not making lunch for everyone in the family, setting the table, stripping your beds and washing bedding, putting dried bedding back onto your beds etc etc. Do this without complaint, be polite. Any backchat over this results in loss of gaming time.
Plus putting in effort for homework, not bare minimum and having X amount of time for lunch so no rushing food down. In school/sixth form their effort grade is outstanding and their grades are high. This shows me that they understand what is expected of them.
They get a huge amount of time on their games in lockdown because they are not seeing their friends, no after school clubs etc so they are chatting to their friends whilst gaming with them. All school work is pretty much done before 1pm but they are up at 7am.
