Go through you emails and find accounts you've signed up for in the past and send as many delete requests as you can. Having old account data lying around is always bad. You should aim to have only the accounts that are absolutely necessary. Try to not always use one email for all accounts too, try and sign up with tempmails (gurrila mail) if you can to smaller forum like sites. but for sites you need email access to, try splitting them up (one email for shopping, one for gaming, etc).
Your operating system is partially an attack vector too. If you're on Windows, try looking for debloating scripts/privacy scripts (windows sends lots of data back by default) and dont use a microsoft account with your computer.
Of course, really i recommend linux. Specifically linux mint, its stable and a better version of ubuntu, its easy to use but still really good, even as a gentoo user i'd still be perfectly happy if i was stuck with mint.
If you have a phone, look into unlocking it. i'm not gonna ask you to buy a whole new phone or anything, but if you can unlock your phone you should. If you cant, try your best to restrict what permissions apps have, try putting telemetry to the lowest level, use Fossdroid to find open source alternatives to regular apps, turn onto airplane mode when you aren't using wifi or text and turn onto wifi off when only using text. There's also the aurora store IIRC where you can download apps anonymously. Sign out of google on your phone, and probably factory reset it too, and never log back into it.
