When I graduated highschool, we didn't have the resources we have today. You can freely learn a language anytime you want. Find out interesting maths they didn't teach you in school, details about the world you live in you might not know (architecture, history, of just why things are one way in one nation vs another).

There are so many fantastic YouTube channels. Here's a list of channel I've subscribed to that I think are with it. There a few programming ones in there too. And this doesn't even cover the channels that showed me how to repair my AC unit, or how to repair my washing machine.

If this lost is to long, than 3 channels I recommend highest is Tom Scott, SmarterEveryDay, and Steve Mould.

I'll add 'Connections' an old BBC series covering the history of technology. The creator shows how one change in one place can affect the world. For instance, Napoleon's armies needed to be fed on the march and eventually we got modern food processing.
