nobody needs to fix things anymore. you just buy everything new. fixing consumer electronics often costs more than buying new shit. you need to move to fixing non-consumer electronics. actually you needed to make that move like over 15 years ago. kek i don't even know how you managed to get any customers after 2015. but since you are into computers you could run a shop that builds computers. most zoomers have no clue how to build a pc or laptop so this might be kinda viable. especially if you do customization etc.
