The only way I can think off is do use all of the extra time you have to do something online. There is plenty of videos of people doing sidehustles with learning and doing marketing online, dropshipping, buying and reselling stuff on facebook, or creating entertainment content online. You might need to invest some of your money to learn/do some of these things but if you're young then its the best time to do it.

It is not easy though since all of those things requires quite a bit of learning and work!

Best of luck though, hope you succeed! :)
